The main issue from playing him is that he is simply out classed from everyone. There are so many more champs that can do what he can but so much more reliable.
He was my main with about 150k mastery on, switched to Tryndamere simply because he is so close to being unplayable in his current state.
They move all his power to his Q and yet give him no options to deliver any of it. Don't say the W counts, as its mostly ineffective and requires co-op to work.
No, he simply has no place in the game at this current time, as he can't be buffed or else he becomes obscenely broken so he joins Aatrox in the dog house.
Truth be told, I actually don't trust that the rework is going to represent originally Morde at all or anything resembling him. If you look at Sion now,
he is a completely different champion than the original. Not going to say he is better or worse, just different. Same will happen to Morde, Its going to be
a different champion that thematically fits, with Morde's name slapped on it.
While this might seem a little dark, I just think this is whats going to happen, I would like more than anything for him to be back, but I don't dare hope,
else I will just be disappointed in the end.
