Hey Tobbns, first thing is that it is impossible to get 1000 Crit in normal games with anyone  but Nasus and even if, it would need you about 20k gold and it will only achieved in the very late game, when game is at 50minute mark and most likely decided already anyway. I mean even if have such long games, its mostly clear which team will win any moment...

The key is to get there. Blue Ez dont need 50minutes, only half of the gold and does more damage than a Caitlyn half-way to her full crit-build.
