Wait morde Is not a revenant (small thematical issue and possible fix idea)
He's a lich, with his armor serving as a phylactery,
AND while we're talking about Morde, can we aderess the fact that thematically he makes no sense? he's a juggernaut, slow super tanks who deal moderate-high damage, but he's the squishiest out of the bunch by far, which again, makes no damn sense for a living suit of armor to be.
Alright well i've said my piece but i might as well pitch a way too make him more in line with what he's supposed too be.
it's real easy, just change what his abilities do, they're all great for what he is they just do the wrong things, heres what i suggest
Passive: Mordekaiser's health scales with 200% of his armor, this will cap out at about 250 armor which means 500 health, about the same amount that a good sion will get with his W passive, so no balancing issues there.
Q: more or less fine as is tbh, no changes needed W: Also more or less fine but give it Armor/Ap Scaling since, again, those are presumibly pieces of his armor E: Rylai's is already core on this dude, just make it a slow. Ult: fine as is, no changes needed
This doesnt really improve his overall power level by a whole lot i dont think, it just makes him make sense. Anyone who reads this i'd love too hear your thoughts on the subject and any ideas you have too pitch too, i know Riot doesnt usually read the whole "NERF/BUFF X CHAMPION RITO PLS" type of posts but i'd still like too see if anyone else in the fanbase is on my side with this one
