Zilean Rework idea
This is general, I don't gave specific numbers, not the best at that.
I feel like his kit lacks options, passive sucks and W is lacking with so few skills, so I changed passive and W.
PASSIVE- get rid of the useless exp aura thing. Never ever seems noticeable. Make his W his passive, cept it activates like every 4 or 5 skills used and refreshes his cooldowns then. Sounds strong but you could go oom quickly so its not as strong as it may sound.
Q- keep the same
W- this is assuming support is primary purpose. Have him reset the cooldown on an ALLY of the last non ult skill used. With the appropriate CD I think this would be a much better W.
E- same
R- same
Alternitivley you could keep the crappy passive and just add my W idea to his current W so he is laneable for those three mid lane Zileans out there.
Thoughts?
