Zilean brief Rewind

I'm
I used to be pretty useful to have on my team with increased xp to my whole team. Oh wait.. Rito made it so i can only give xp to a large portion of summoners rift. Oh wait.. They nerfed me even more than that, didn't they? I can now now only give bonus xp to my whole team if theres a team fight and our isn't balls deep into the fight, atleast i can hit them with my timebomb and rewind just in time for my ult. Oh wait.. Damn you rito! Now i have to throw a time bomb, hope that i don't miss(or they run over it), and my rewind is completely useless to the cooldown of my ultimate ability??? GG.. not or feed
