Honestly, when I play Tryn i do not do very well, but I have been killed by him plenty of times. But, this can be said for a lot of champs. I really think it's rune usage. People who take Tryn seriously build runes/mastery pages for him which makes him a very powerful champ. But, I mean, what else would you expect from a dps/carry?? That is his JOB! Now if you had this complaint about, oh idk, Soraka maybe, then I would agree about having to nerf. But this is not the case. Nerfing carries eventually means...well... no more carries left! You should try playing Tryn yourself and getting a feel for the big sword, then maybe you will understand!
