Akali vs malphite ult

Why does Irelia's Q reset when killing a unit but Nasus' doesn't? It's simply absurd!

malphite is an unstopable force

Because Malphite has no other way to engage on target, unless he walks his slow bulky ass up to them and presses Q. Akali can E, Gunblade, ult once, ult a second time, flash, and get a ms boost in her W.

Different champions require different things, it's almost unreasonable to expect a tank and an assassin to require the same things. It would be like wondering why malphite doesn't get an invisibility shroud. Answer is generally that the champion doesn't need that thing and including it would sure up a weakness that is needed for the champion to be even remotely fair to fight.

Yes why have counter play? counter play bad take away please.

why are we comparing two completely different abilities that are supposed to do two completely different things and are on two completely different champions?
