Everyone has played Vaal fire ball to 100 this league multiple times. Not sure what linking a twitch profile has anything to do with your lack of knowledge.

Hmmm well obviously if you're using mirrored gear and legacy stuff... I mean if your build is hundreds of exalts, it has to be rewarding to play it.
Any normal player doesn't usually get rewarded that much from running their T15-16's.

Also reading all this I'm starting to think I really haven't played enough different builds!
