Because there is no "meta." You're the one that's limiting their view of the game. I'm looking at all 100-plus heroes. You're looking at 20-30 of them.you cant adapt your view on a new meta.
Except not. He's strong at all stages of the game.This is not the case anymore. Now early game advantage matters alot more, infact mid game is currently the least important on the 3 phases, the phase which troll is at his strongest is the least important. You either get your early lead to victory or you bank on late game. Both of which troll can lose in a multicore meta.
