does lp gain/loss have any basis in your stats that game?
Does your overall performance in a game have any affect on the lp you get/lose?
Personally I think it should because I don't think it's fair to make someone lose lp with matches being so random as to whether good players are on your team. Like when my top and mid laner have both died before I finished clearing my red camps, but my bot lane wins lane and gets tons of kills, and we lose the game, I think that the bot laners don't deserve to lose the same amount of lp as the mid and top. Or vice versa with any of the lanes/roles. If someone's doing really good but their team is doing bad, do they really deserve to lose as much lp as the rest?
