lol I think many people in plat have ego problems. I am gold 3 atm and when I was in my promo to g3 from g4 I duo'ed with a plat 5 buddy of mine. Strange enough I was the ONLY gold player in that game and all of enemy+my team was mid-low plat except enemy trist who was plat 2.
The moment I got into game I started getting flamed on just for being g4 (srsly thats just pathetic). Our top laner called me elo boosted trash who will feed 30 kills and I was even told to go afk so they could remake lol :D Funny thing? I won my lane and our top laner fed instead. We kind of stomped that game and won. I went 8/3/10 or something and after we won as you can guess , enemy team was flaming each other hard.
