I believe there should be a balance team dedicated to ARAM.
The few changes made to ARAM for the Curse of the Drowned event gave it a bowl of fresh air. The gamemode became healthier and more interesting. But I truly believe there could be more to ARAM. The gamemode could be so much more if there was constantly changes specifically made for it rather than just a copy past of the Summoner's Rift balance. I would love to have a balance team dedicated to ARAM that could keep the gamemode fresh and exciting.
