Why Not Play... Mordekaiser

Okay so I may or may not start doing this occasionally, talking about underused champs and discussing why they're underused, but anyway here we go.

Why not use Mordekaiser? So I've played a few games with the dude and his new bot lane carry role and I gotta say, whether good or bad thanks to the meta, he's pretty fun to play. I honestly don't think he has many problems insofar as gameplay is concerned, though others may disagree. This has lead me to believe he needs what I call the Kassadin treatment. Now what is the Kassadin treatment? Well let me tell you a story. Long ago, right before champion mastery was implemented, I played the old Kassadin, before his VU. I loved his playstyle but I wasn't able to play him for more than two games in a row, and I couldn't place my finger on why. When his VU was released, and shortly thereafter Champion Mastery, I played around one hundred games straight just using him and he was the first champion I ever got to mastery 5. I learned why I couldn't play him often. Kassadin simply used to be UGLY. I loved his playstyle but I couldn't get used to how bad he looked. once that was fixed he was perfect for me. I believe Mordekaiser's popularity just might raise if he was simply given a nice visual update. I mean, SERIOUSLY, help this dude out. He currently suffers from the worst case of pizza-feet in league, give him real feet. His cape is this ugly triangle shape, make it long and flowing, like Tarics, but grey. Maybe a few shards of metal around the edges. And lastly, the dude is a midget. cmon boi. this is the MASTER of METAL. LOL MAGNETO. apparition of the shadow isles that commands undead LEGIONS. Make him BIG, make his iron muscles bulge, make his mace spikes consistent and symmetric, not random. Build him similar to Nasus, a hulking, lean, muscular beast that will freaking end your life with flying shards of metal, steal your soul and use it to kill your best friend. This is MORDEKAISER, not S3 Twitch. That may make him more popular. Also, side note, what if his ultimate had a three second channel, once he killed the thing he marked, and it showed the enemies soul standing there as he encased it in metal?!?! It would keep up with his shadow isles enslaver thing, actually make it look like it could do damage instead of being a silly ghost, and look FREAKING AWESOME. Anyway, just my thoughts, tell me what you think.
