Mordekaiser's passive, once activated, should not be able to refresh after just one attack
Right now it is way too easy to keep his passive up as he only has to hit you with 1 autoattack or spell after activating it, that makes it near impossible to trade with him as a melee laner. Suggestion: It should only refresh if he hits another 3 AAs or spell.
can poke him safely and has a dash to escape his pull along with comparable lifesteal sustain if not better.
can trade evenly and if timed right can invalidate Morde's shield with empowered W, also the better life stealer.
