A matchup of Tryns is determined purely by luck

Not even close. In bot lane, you have skills shots and supports. You have completely different kit differences. In a 2 Tryn matchup, you have AA vs. AA. One gets lucky and crits 2 times in a row while the other doesn't, they win.

You're trying to take my specific example and extrapolate it to something completely different. Please don't try to do this if you aren't intelligent enough to do so.

Tryn sure is annoying to play against. That wasn't this post, though. I was saying a match of Tryn vs. Tryn was luck lol. I played a Tryn last game...we fought a lil and he got 2 lucky crits in a row to my 1. Well, there goes lane lol. He now has item advantage and a huge pressure advantage. I got lucky and got back into because he made a dumb mistake and stayed in lane too long with no health. If he didn't do that, it would have been completely bullshit haha.

You know, I thought this marksmen update was going to be a great chance for them to start removing crit. Instead, they made ADCs focused around it. Then you have entire champs like Tryn and Yasuo focused around it (well, actually you can't really say Yasuo is focused around crit. He has way too many things in his kit to be "focused" on it. It's just like an added lil bonus for playing the bullshit champ). I don't know, disappointed in the way they made a major factor in the game based on luck.
