Why does Mordekaiser still have health costs?
With the new rework being a sad inevitability, I can't get over this small fact that he has health costs on only two of his abilities, Q and E. Q costs 32, E 72. Okay, but why? These are so negligible as to not even be that gating -- right now you should be maxing E last in almost every situation barring maybe some hopeful mid build giving him poke; since W is free with a pretty sizable heal, and Q has very little actual cost, he has absolutely no troubles with sustain in a duo lane. If anything, it's more problematic for solo-Kaiser, whether in lane or the jungle, because he still has those health costs, however marginal, without the benefit of his powerful sustain.
So why are they still there? You can negate all of it (in a duo lane) with his W and he's an incredibly not-bully laner everywhere else. It seems like.
Now, granted, they ARE very negligible now because Mordekaiser has been stuffed into a mostly tank build, but I would like it if only so people can stop rushing spellvamp on him on the PBE.
Was there some sort of consideration as to why these still exist if you're going to give him a giant heal that cancels it out anyway?

for 52% Lifesteal and 35% Spellvamp all increased by 20% of the incoming health, and since he works well with both AD and AP this build would totally work on him and basically make him ignore any health costs he has.
's rework ever hit live, this wouldn't be an issue
and either Tabi or Merc's as your boots. Situational items would be
you don't need lifesteal or spellvamp, those are trap stats on him.
