Riot! Modekaiser changes, and why they won't work.
Okay, first of all, it's nice that Mordekaiser is finally being looked at. But these changes will not make him a viable, or even an attractive pick.
For starters, why pick Mordekaiser over any other tank? People will not look at him and say "Oh my.. that passive! Always shield, never die!" Nope. Even if his shield made him nearly invincible he still wouldn't be picked competitively. The reason? He is more or less completely outclassed by a good majority(if not all of the other) tanks and bruisers. Okay, we got it, you want his weakness to be getting kited(I'm sorry, but this is a piss poor excuse for a weakness in league of mobility). But the fact of the matter is he won't ever be a good pick if pretty much every viable champion in the game can kite him with ease. Mordekaiser has no way of sticking to his target. Sure you can get the crystal scepter, but it's effectiveness is minimal on Mordekaiser, seeing as most of his attacks are AoE or DoT. There's just no winning with this champion. Mordekaiser is so devoid of utility, and he gets nothing spectacular in return for it. Yes, his ghost is good. But in the end it isn't powerful enough(and certainly not reliable enough) to make his entire kit weak, and dependent on him getting a ghost(his ghost can be easily kited also, and even 1 CC can let you escape it).
If you want Mordekaiser to be a good champion, he needs some serious changes to his kit. It's outdated, and comes from a game where point and click stuns were the norm. Just modifying his numbers a bit won't fix him, he needs a complete rework.
