He just extends the game to the most boring 35+ minutes of your life by threatening a side lane and E’ing away. No solo laner can match him because he’s very interactive with R.
Playing ring around the rosie for 35 minutes and hoping your team knows how to outplay him fucking sucks.
I think the best thing to do is just build bramble vest/ anti heal first and steelcap boots item even if it means I don’t get my normal scaling. This typically slows down tryndamere long enough so at least one of the other lanes gets a break through
