Zilean needs new Passive
Season 4 Zilean was on the op side for 2 reasons .
- Spellthief combined with long range of his Q gave free income without much risk.
- 8% bonus exp gave primary roles 1 level advantage over their opponents .
Still Zilean is not a good champion in 2 vs 2 . There are many counters like Blitz,Alistar,Taric,Fiddle,Janna,Thresh and other .
There hole point of picking Zilean was that 40% of total bonus exp . Now its 16% ( technicly even less because you not gona be by ad all the time) . Its not worth it! Imagine cutting down passive of other champions by 60% to 80% ! It would make them useless .
Without global effect his Passive doesn't really help you in bot lane at all . You will still likely be behind because other champions can zone you .
Here are few ideas:
Timeshift - When Zilean uses an ability it reduces cooldown for all friendly champions nearby by 0.5 second . I think this will help Zilean with late game teamfights considering that he spams his abilities .
Distorted Dimension - Zilean has passive aura that slows all nerby champions by 3% . This aura would help support Zilean poke more safely and also help mid Zilean as well .
