a side note if i may...
ARAM should the game mode you take the least serious ... its 10 people with "random" champs in a "run it down mid" map where you smash buttons have fun and rack up kills and damage... no need to report or flame or anything
yes you can use it to work on "team fighting" but not really considering team comps are completely random and every one goes full damage most of the time. and most of games are legit won by luck of draw with champs.
it should be the idgaf game mode to mash buttons kill shit and have fun nothing more
