Mordekaiser is so fucking broken its not even funny anymore

So, Mordekaiser huh. He looks cool for one, but if you take a closer look at the cool iron man, you can see that along with his cool looks, his kit is as broken as shit. Sure, as an inexperienced player like i starting off playing him, i cant really know how to carry with him until i get better, but is so fucking broken that i can just play him first time in ranked, mind you, and just start shitting on everyone like im already a level 18 garen with 10k health one shotting you from the top tribush at level one. his shield is like completely broken at the mid game where if my W is up i can just Q a minion wave and get all my hp back, and apparently the only guy ive had problems with playing is where he shits on me because I cant land my %%%%%%%%% grabby hand. complete busted champion that insta wins the game if you have a brain. and also, if you get put in the demacia realm you instantly die to a giant metal man going rough on you
