Changes idea for Tryndamere

So this champion is broken as hell. This is not a "oh this guy must have been rekt by a tryndamere" thread, but a thread that recognizes tryndamere is broken. Tryndamere, is a broken champion because his ultimate lets him become invulnerable for a few secounds, so he cannot die, but he deals a lot of damage. Trading with him can sometimes also be a little annoying and unfair because his passive gives him 35% crit chance and he can also heal back up. These are the reasons why tryndamere is over powered. So here is what I suggest:

1.) remove his mobility, take away his ability to dash with his spinning slash, he should not be allowed to just spinning slash on top of your adc and just rek him, or when his ultimate is about to wear off, he can just dash over a wall. This is really unfair, since he can just ultimate and at the last seconds just dash away or when you are trying to run away he just dashes and catches you. I think darius is actually balanced because riot did a good job of giving him very little mobility so you can set up ganks and stuff and snowball early, but you cannot do this with tryndamere. I propose to make tryndameres spinning slash more like katarinas w, and just do aoe damage around him. So basically just remove his mobility so he cannot dash over walls or dash on top of you or dash away. I think his w is fine the way it is. Its just a slow.

2.) Change his ultimate/passive. Maybe his passive can be a rage bar but the rage bar does not give him crit but shows how long he can go invulnerable. The more rage he has the longer he can ultimate, the moment he ultimate's his rage disappears but he can remain invulnerable for a few more seconds, this way he cannot just e away and q so he heals back up because he will not have rage to heal up a lot. This would be so much better because its annoying he gets rage for clicking r and than just destroys everything. This would make tryndamere a more balanced champ
