I like where the mordekaiser change is going but it's lacking quite a lot of things...
he's rewarded for building health which is a step toward tankyness. optimizing his survival during team fights.
but here's something you might have forgot , he's the only tanky dps with no crowd control movement speed or gap closer.
i love the movement speed on ally change but could you consider this? imagine if , just imagine IF mordekaiser W could be used on enemy champion to either slow them or give you movement speed.
I mean you can be tanky all you want but if you're just going to sit there taking hits it I don't know it be the same as before you'll just die in the end...
give me a reason why i should play mordekaiser over any tankydps to be precise what does morde have that other tankydps doesn't have other than his ghost that isn't 100% guaranteed like yorick, especially when you're facing zilean,GA or even QSS in all honesty i will reply: people can just walk away from you because you have no crowd control movement speed or gap closer.
that's how I feel when I play mordekaiser.
what i'd do if I were you i'd reduce the duration of his R by half this way he'll be doing more damage over a shorter time since his ap ratio has been reduced this might help out dish out more damage while staying tanky, same for W i'd make it cast-able on enemy champion reducing the duration to dealt more damage over a shorter time, making you gain movement speed when moving toward enemy champion and probably slow as well.
that's my vision of mordekaiser.
