Trynda in URF
Should be disabled.
Let me get this straight. Ive never once complained that a champion is OP or anything like that. And i dont think Trynda is OP in any way in "normal games". I just think that he is too strong in URF. And its not the damage he can deal, his perma slow, E every 2 seconds or his ulty. Its one on its own, or if you combine 2 of them together they dont exceed what other champions can do. Its the combination of these along with his ulty, which, as every other champion, has a very low cd. You simply cant deal with him. He will get to whoever he wants and burst them down, all the while not dying because of his ulty. Even if you manage to stun-lock him, he can still use his ulty and needs just a split second to run away, if he doesnt E on your face and smack you. And all this is getting worse once the game reaches late and he starts stacking more HP and stats overall from excess levels.
You can argue that other champions like Master Yi can deal as much or even more damage than him, but you can stun-lock them and kill them. Then there is Kayle, she can survive with her ulty, but the amount of damage she can deal is not as high as Trynda, or at least not as bursty, nor she can stick on you as easily, plus if you stun her the right moment she can die without using her ulty.
Last game i played as Mundo vs a Trynda. We smacked him hard early-mid, to the point i could solo kill him and everyone else in my team could at least escape, force him back, or buy enough time to waste his ulty. We broke all 3 inhibitors at some point. And then came Trynda late game with full build. He was able to easily 1vs1 me, which isnt a huge bother, he is not OP because he could solo kill me. But he was able to just win fight 2v5, we just couldnt kill him. And i played another game against him, before that one, where we could kill him only 3vs1 and he would pick at least 2 kills.
So i suggest he is banned from URF.
