Any hope for Tryndamere to ever be fixed?

And what I mean when I say this is when is he going to have his ultimate nerfed to automatically trigger when he hits a certain HP threshold so you can offer counterplay to champion who's counterplay strategies involve "Stack CC and end the game fast"

That's not counterplay, that's just plain stupid. Especially since LoL has no items that offers hard CC. You can only have a champion like this exist in a game where there are different avenues to counter faceroll right clickers with no skill involved if you have forms of external crowd control that can be picked up on anyone.
