Anyone else get to spend some time playing ekko yet? I'm really enjoying the playstyle. A few reasons why - his e (this is a dash to anywhere, followed by a dash as long as you click on a target in range (must be enemy - works on enemy wards though). My absolute favorite thing with this is being able to quickly reposition to avoid dmg or position for a combo. I found it fairly intuitive to use and only took a few games to a really good handle on it.
I like the q as well - folks still aren't used to it, ofc, but I think its going to be fairly easy to utilize for poke. It also is incredibly good for wave clearing (and satisfying at that) - his passive + w passive make it even easier as you proc your 3rd hit on the creeps to easily pop them, even with low dmg output.
His w is quite a bit less satisfying in mid, but still very nice vs melees out of top. In mid, you can at least ensure that you can place it and get a shield for it, but I found that it was pretty easy for the enemy to avoid. The ideal usage is either using it to intiiate a fight (lower odds of success, but if you are successful, the dmg output is very, very high) or tossing it up during a fight which forces the enemy to reposition or pay the price. It just seemed way to easy to avoid unless things are going crazy (which is fair because its a shield and a 2.25 sec stun). But, its easiest to land if folks are in melee range... which makes it so much nicer to use in top vs melee.
I tried him in several roles/functions. Not a fan of him as a jungler, though it is somewhat doable. Mid as straight ap is strong, but requires a higher skill cap imo. I also really liked him as a straight bruiser tank out of top. His kit is a cc machine. His q is a slow that is easiest to proc if he's in close combat - if he takes too much of a pounding he can ult out or just ult to do added dmg/regen. Up close and personal when things get crazy, his w is super useful. He becomes a lowish dmg output beast that slows and stuns (again 2.25 sec stun or so...) it's like bard's ult if it wasn't garbage (eg enemy team stunned, you and your team can go wail on them). I played him a s bruiser with frozen gauntlet - very nice as he's melee and you get the strong slow... plus you built in slow... plus your gap closer so you can stay with anyone... plus your stun... CC BEAST.
