When Tryndamere gets reworked...
Don't put his spin and his slow in the same kit. He already has a gap closer, he doesn't need another ability that impairs movement once he's already cleared the gap between him and his target. Also, don't give him an ultimate that makes him unkillable, that's probably the dumbest most brain dead thing in the game. If you want to keep the undying theme might as well give him an ultimate that gives him hyper resistance but can only be activated below a certain health threshold, that is better than not dying period.
Thought, i'd post this in hopes that riot doesn't make the same mistakes with Tryndamere 2.0, this champion is complete nonsense to deal with in solo queue, especially if you are trying to stop him split pushing and you don't have inbuilt cc. He'll just dive you and some times it is necessary that you stop him even though there are better champions for the job but people don't like guarding split pushes and ignore it for whatever reason in solo queue. It is actually the worst thing ever to try and stop him then you get flamed for letting him push 2 towers after he just dives and kills you.
