Tryndamere In Urf. Can this not be a reality?

So. as Ive come to notice, and I'm sure many others have probably come to see. Tryndamere is a bit broken for Urf. To the point that it drains the fun from the gamemode. The list of Banned champions Urf needs one more spot, and I believe that spot belongs to our large sword wielding friend. Seeing as his ability to negate damage entirely....for five seconds......even if CC locked. can allow him to easily 1v3. I watched as someone who was clearly new to Tryn learn what it took. to flatten my team without much effort. I understand Urf is meant to be a crazy op environment where everything is set to 11. but this is just excessive. Tryn is unkillable at level 6. and from there it is far too easy for him to become a monster. Please can we either re enstate the banning feature in Urf. Or entirely remove tryndamere. Too many games ruined because of an unkillable madman that doesnt even require skill to make use of his devastating power. and I wont even begin to talk about AP builds
