After thousands of matches I have concluded that the ability to be invincible, while still being able to do tons of damage (followed by a burst of healing after) for 4 seconds is inherently unhealthy for the game. Even unfed, he still becomes a problem. Hes a problem fed. He's a problem unfed.
Got some news for you.
AOE Trynd Ult :O
His kit is dumb, but hardly a problem. He's a pub stomper in low level play and a super annoying split-pusher that is otherwise sub-par everywhere else.
He has glaring strengths to compensate for glaring weaknesses. Tryndamere without his ult doesn't work. Riot recognizes there are unhealthy mechanics in the game but the idea is that every champion gets something to hold their own.

ekhem 
Are unhealthy too then . Especially Taric
EDIT : You dissapoint me dude , i'm subbed to your YTB channel .
i feel like his ultimate is buggy.. like sometimes it doesn't last as long as its supposed to..
Shouldn't poro snacks being an icecream sanwich of some sort? I mean they are native to freijlord where everything is frozen so a frozen dessert woudl make more sense
"Thousands of matches"
Dude, you are bronze right now and were silver last season as an Aatrox main... you know nothing about how to counter trynd, he is actually easy as fk to counter its called "kite" here is a list of champions who can "kite" trynd during and before he ults
I would keep going but I think you get the point, everyone can counter trynd as long as they aren't actually brain dead, with right items and even a 'hint' of cc he becomes more useless then... well... 
who ironically, can kite trynd very well
(btw, this is not disrespect, I respect the aatrox main thing, but seriously, he is not that hard to beat.
