the reason the 15 minute surrender is up so often is cause one lane gets smashed and the team more often than not gives up, and starts playing as such. noone considers having a bad game, or even try to think of playing late game, ive seen it time and time again, people flame one person for being bad not even knowing all the cercomstances that lead to one death, or god forbid someone makes one mistake, gets on their case and end up throwing the game cause they starve that one person of resorces or refuse to play with them, the 15 minute surrender that happens so much is because people just give up and dont try to come back. not saying that there isnt a bit of a snowball issue in some cases with certain champs, but instead of surrendering unless its like 15-3 or some ridiculous kill/death count like that, or all lanes have lost, get back in the game, or atleast make an attempt to..... and better yet, try to actually help instead of flame one person unless they cant get back into the game... dont make it worse for them by harrasing them to the point that they dont want to play, or starving them more in game.... ive seen mostly jungles and supports do this, they make an opinion about a player, and instead of trying to help their team get back into the game, they try to either be the hero, and starve the player, or give up on trying to win compleatly, not saying other roles dont do it either, but these two have more opportunity to do it.
needless to say, stop playing hero, stop being a dick, and stop acting like your phsycic
