I started playing comp in E4:A3 and reached S2 back then. Now I am P3, and it looks like I could rank up to Diamond within just a matter of days. When I played with my friends, they asked me how it is to play in high elo.
I told them that plat is certainly not high elo, but I was not sure how high and low should be clarified here.

What are your opinions about it?
