Aram is a boring mode that does not promote skill. Its a goof off and take it easy kind of game mode and nothing more. 90% of the people who take aram seriously will not rank higher than gold in ranked which shows how good they really are.
Aram is a great mode if you wanna relax and chill and just pick a hero for goofing off and change of pace which is quite acceptable but trying to change the game mode to help wins and losses matter is honestly totally pointless.
Oh and afks in that game mode are 100% terrible
