maybe look closer on things, using simple math, and approximations (based soley on this poll) out of 3922 people
600 would be willing to pay 10 bucks, thats 6000
500 would be willing to pay 20 bucks, thats 10,000 (note that with less people you still make more)
250 would be willing to pay 30 bucks, thats 7500
75 would be willing to pay 40 bucks, there's 3000
and 125 would be willing to pay 50, thats 6250
so judging by this poll alone, about 60% of the people would be willing to pay nothing if they didn't have to, want to, or see something they couldn't live without.
the other 40% would market a value of 32,750 and that doesn't seem at all bad to me. Premium skins could be looked at like this, they are the mercades of cars. Now about everybody has a car, but not many people have a mercades. But the company doesn't say, well guys, most people don't buy our car, lets just call it quits. Instead they realize what percentage of people is their "market" and sell to those, and as you can tell are doing quite well. in the premium skin case, it looks like about 40% of our users are the market and those are the one's we need to worry about.
