really a zilean op thread?
(insert facepalm pic here)
the real problem with zilean, is that they keep changing his passive the wrong way, enough with the exp crap. just give him something new that actually does something. his current and soon to be new passive will be 100% worthless when a game reaches the 40-50 minute marks.
maybe something like
casting a bomb on an ally increases their move speed by 10% (stacks with E)
casting a bomb on an enemy reduces their damage by 10% to zilean for the duration
maybe not those exactly, but make his passive actually do something.
