Fix Zilean and Shyvana, 2 of my main champs. HOW !
Zilean passive gives experience, probably one of the worse passives in game. Instead of XP boost, change Zilean passive so that he could drop bombs without a need to stop aka "drop bombs on fly". Fix Done.
Shyvana passive benefits from dragons and it makes her super predictable, meanwhile she has no CC whatsoever. Instead, change her passive into somewhat Udyr's Bear Stance, that's all Shyvana needs to be great again without overpowering her.
