Shyvana really needs a new passive
Currently Shyvana's passive, for those who don't know, gives her bonus damage towards Dragons and will grant her 5 bonus armor and magic resist for every dragon her team has slain. Essentially this is a passive that is reliant on your team focusing dragons and based on the rate you take dragons will drastically determine your tankiness.
Honestly this passive just needs to go entirely and replaced with something more overall useful, rather than a potential heavy snowball mechanic tied around dragon taking. Currently her kit is just damage, damage, and more damage with a touch of tankiness added in Health from ult and resistances in passive, let's give her some utility whether it's healing, slows, or something super creative (probably not hard cc she doesn't need that).
