#gp-mid:
Sure, Cow wasn't playing his strongest champs. But you also "stole" Karl's role. Karl can only play Cho in a solo lane (from what i've seen), and even though i do think he should branch out and generally has good jungle sense, occasionally he has unrealistic expectations from laners - so the expierence is good for him in some ways. But, from the get-go the roles were distributed in such a way you weren't playing for "best win chances".
#blue-donations:
Junglers can pretty much be seperated into one of 3 types:
1- AD junglers
these guys usually don't really need blue, but do get amplified somewhat. Nocturne loves the 20% CDR on his ult, Udyr is somewhat mana-gated midgame (though blue doesn't really help his ganks at all except the fact he has less mana problems while jungling).
i'm pretty sure Vi can solo dragon if she gets 2nd blue.
While taking blue is a boost, they function adequately without it.
2- Mana-Gated AP-based Junglers
Skarner, Hec, Fiddlesticks, Amumu, Naut, Diana
These guys get significantly amplified by getting 2nd blue. Their ults CD's are usually pretty long at rank 1 (but not rank 2/3). They have super fast clears if they are allowed to spam abilities, but mediocre otherwise, and so their clear speeds are way faster. Most critically, like you said, they hit level 6 if they take first blue and that lets them make a big power play rather than having to go to Red (and then being only at half-2/3rds mana).
These junglers are typically where these "is blue mids or junglers" arguments typically revolve around.
3- HP Tanks
Sej, Zac, Voli, Cho
These guys really have no mana problems.
If you are a #2 type jungler, you typically have a few options:
1- Use 2/7/21 masteries instead of x/21/x. Those masteries are really good on those people.
(speaking of which: don't use Legendary armor on anyone. It is 2/3.5/5% increase of the armor/mr you get on ITEMS+runes+masteries. It doesn't include your base. With your endgame build those 2 points were giving you 1.8 Armor and 2.7 MR - that's awful at level 18 for 2 mastery points when you could have gotten 1.5 Armor+MR at level 1 instead. Maybe just 1 point is okay because it gives a full 2% of both instead of a diminished 1.5% compared to the already-diminished flat 1.5 Armor/MR of just one).
2- Build Mana/CDR:
You didn't build SotAG (10% CDR, HP with someone who has an HP ratio...). You did build Shrelias way later in the game for some reason.
Frozen Heart is also a really good item on these junglers that also gives a bajillion mana + CDR. You didn't build a Glacial Shroud. Now, Cho ended up building FH and so building a second one of those would have been bad. You should blame Karl for doing that. (AP Cho with blue will do more damage than jungle Naut with blue - having him take the blues while you built FH would have been more optimal).
3- Take 2nd blue, make your power play, but give up everything afterwards. The funny thing is, there are really only two lanes you should make a power play if you take 2nd blue - botlane or midlane. If you kill the enemy mid lane, then the deficit has been made up (esp if your midlaner takes the kill + blue). If you get a good gank botlane, you can get dragon which also makes up the deficit If you take blue then gank top... well you traded an advantage toplane for a disadvantage midlane.
Note that giving mid blue is akin to constantly ganking them. The amount of pressure blue exerts is massive. A mid with blue can push to tower, then either roam or take Wraiths, depending on the situation. Additionally, giving blue mid gives a huge chunk of additional EXP just from blue. Remember if 2 people share EXP, they both get 70% of it. So if you give up blue, you lose 30% of your exp - and typically end up just a little short of level 6 which is a bummer.
But you're giving your mid an entire wave of EXP that they wouldn't have gotten. i have gotten 2 full levels against mids who weren't receiving blues by getting 2nd/3rd blue and taking wraiths. Without even ganking or anything you've put mid into a controlling and dominating position.
This is one of the reasons why it is a really good idea to give Energy-Users like Kennen, Zed, and Akali blue even though they don't have mana. They do benefit enormously from the levels (to prevent falling behind), and they still really really really really like the CDR and energy regen. So you should probably give them third blue.
A midlaner that is a level behind is much weaker than a jungle that is a level behind. Because while the midlaner has to deal with someone actively trying to kill them, the jungler gets to mostly sit in the jungle and PvE.
Of course, if your mid is losing really badly, or is against someone like Kennen (or Fiora) who can't easily push and probably isn't getting blue either, you should probably take the blue.
The rational that Naut has awesome ganks with blue... well, even though your ganks are great and all... mid lanes are better. Mid lane has 1-3 levels on you, has just as much CC typically, and does about twice the damage. Even better than a midlane gank is a double gank with both jungle and mid. This can't happen if your mid is pinned to tower.
Falling behind in EXP? Most mids are fine with letting you take their mid farm while they do a gank on your behalf. Or letting you take their midlane while they take blue.
If you mid is pinned to tower, and you get invaded/do invading/ they are doing dragon... they can't really react. They really can't just walk thru the minions - they'll get engaged on. They can take the long way around, but that adds 5 seconds of travel and the enemy mid is already 3-5 seconds ahead just by being in a better location in the lane. Even if they are able to react, your mid laner just lost about 100 gold + 1/3rd a level. It's basically like giving the enemy midlaner an assist each time your mid have to leave the lane while it is pushed to tower.
#wards:
Pretty sure Ms Swan bought way too many pink wards that game. 15 pink wards???
When I jungle, I always want all of the jungle buffs. They are there for me
well you want all the buffs all the time
You take 17 minute reds, and you get pretty angry if you don't get 2nd blue when you're AP Yi.
karl - do you really camp folks much at all when you jungle? With naut, I'm often waiting out of sight for a good 20 seconds (by often, I really mean 2-3 times per game).
Sitting in a bush ... "out of sight" ... leads to a lot of bad things. Frequently you aren't out of sight and if you're in a bush for 20 seconds it typically means Countergank (though not always the case - see that one time we had a Rammus top and Katarina sat in the tribush for like 20 seconds and i did nothing but push the tower because the rammus was 0/2 and 30 CS behind - not worth saving and if performed badly could have turned into a double death for us). It's kinda that funny thing that happens sometimes:
Someone calls for a gank, they get it after sitting in a bush for a bit, burn a few flashes but no kill or damage. Jungler goes home... and then 5 seconds later the enemy jungler + mid show up and slaughter the lane and then take dragon. WTF 3 BOT WTF.
For every action there is an equal and opposite reaction.
If I'm running anivia, udyr should give it over. If I'm being a sport, though, then I'd take a champ that isn't as dependent on the blue so he could take the 2nd one.
heh.
