I hover around 2.5k, so nothing too special but I have noticed it is less frustrating the higher you go. It's no less toxic but it is at least more common to find a team with a proper comp and fundamental understanding of the game when you are at 2.5k say compared to 2k. I've seen a lot of people say that its all the same all the way up to master. It's not. Well at least I don't think it is.

Put it this way, when I solo queue at 2.5k games seem to be much less of a headache. Compare that with when I queue with my friend who is usually <2k and there is a clear difference. Of course not every game holds true to this because you are going to run into certain people that a throwing/tanking or just trolling but yeah that's my experience.
