I haven't had a chance to really read every single post here, so maybe I've missed this somewhere; but, I'd really like to get an explanation as to why Mordekaiser isn't Tier 1 or, at the very least, high Tier 2?
His farm (regardless of how well he gets pushed out of lane) is near flawless, his mid-late game tankiness/burst (by building WoTA/Cap/Liandrys) is absurd, and he is 100% a #1 target....being a #1 target means...you can't let him just sit there and melt your team, you have to prioritize him with ignite/cc. If you don't prioritize him, his burst is such that he can bring down multiple champions to around 50% HP in 1 rotation, while simultaneously harassing/dropping your primary target to around 0% health. Not to mention, that shield's consistent damage +spell vamp. is seriously hard to counter without a high-burst team comp.
On the flipside, if you do prioritize him, then the other two champions that are on his team are set to eat you and your team for the 4-5 seconds it takes you to burst him down.
I personally keep him as a perma-ban in 3s up there with Darius and Yorick for the below reasons:
1.) High natural tankiness
2.) Fits in any team composition
3.) Not reliant on other champions to be devestating
4.) 1v1 capability is extremely strong
5.) Harass after level 4 is extremely strong
6.) AP Tower pushing, stronger than most
7.) End game team fight capability: Unmatchable
1.) First 3-5 levels, he's weak to ranged AD and Bruiser CC
2.) Requires a commit on most team fights to draw focus
3.) If caught out of position, can be locked down with ignite/cc.
4.) Slow in most builds
Let me know what you think, I'd love to hear your thoughts!
