So i just gotta ask.....

I've been playing league for a little bit (since about the release of vel'koz), and i LOVE all the void related champs. I even bought rek'sai right when she was released. Which leads me to my issue.

So i just gotta ask........how am i supposed to play/build rek'sai

because when she came out i played her as bruiser/assassin, then she got some nerfs and i tried to play her as a more opportunistic assassin/bruiser; then she got some more nerfs, and i TRIED to play her as more of a tank(which failed horribly). ever since about her 3rd nerf i haven't been able to do anything tangible with her. If i go damage i get vaped before i can hit anybody, if i go tank I DO ZERO DAMAGE, knock a guy up maybe(thanks range nerf) and ,if i don't have atleast 2 def items, get vaped.

i just need some suggestions, i loved rek to start with(and i main jg) and i was really excited to have her as my new main, but with out damage or survivability i just dont know what im supposed to do with her.
