Well, I rarely lose when playing against a Tryn. Good or not.
Generally, a Tryn player over reaches.
Tactically, all you got to do is hit and run, whittle him down, then burst him before he can hit his ult. Even if he gets it off, just retreat. Often in a panic for a kill he'll chase you and your going to kill him in the 7th second.
If he plays timid, let him. A timid Tryn is useless. Don't chase, just harrass. Force him to use his ult to get away, not to get kills. I really don't fear Tryn at all.
Not with Poppy, Olaf, Fizz or any other Melee Champ that can beat him with a little "fighting retreat" action.
That being said, if you play TT, in my opinion you need a quick escape at the ready at all times. When I play kogmaw for example, I often take FLASH and GHOST just to give me an out if a Tryn or similar get in my face. and while Im running I can still pound away with the R.
In Summary, beating Tryn is all about Feints, Flanks and ambushes. Charging in, toe to toe, if this is your style, will give you the impression that Tryn is OP. He aint.
