Because the actual game is fun as hell, it's the meta and team play aspects I can't stand. Losing a game because of other people, and even winning a game because of other people, not very interesting.
I have never complained that someone won because they picked Centaur. You're still confusing my arguments. Trying not to sound too arrogant here, but I could very easily fit into coL or EG as far as American pro teams go. I was actually invited to coL already. It is virtually impossible to have more experience with this genre than me, I have played DotA since the earliest versions and I played games like AoS before that. Even back in the infant years of WC3 when "MOBA" was just "hero arena," I was there.
I think of myself like chess grand masters. It's not so much supreme intellect or massive skill that makes me the best, it's just pure experience. After some tens of thousands of games over the majority of my lifetime I really have seen or thought of any possible situation for the game. The biggest issue here is that I'm still playing with new players because it is a team game, chess GMs don't have to get frustrated like this because their game is 1v1.
