I'd quit LoL if my friends didn't play it so much... I don't even have fun anymore. Everything is just a painful grind to try and get back into plat. I end the day feeling like ****, and regret not meeting my goal for the day only to realize I have responsibilities.
Nothings worse than being 1 game away from your goal, then going on a losing streak and ending up worse than you started that day, then realizing you have to go into work the next day/have tons of class work to do.
As for "just playing normals", I hardly enjoy that either. Game feels stale but I don't want to ditch my friends.
