Blizzard applied some hotfixes over the past few days that should help make the maps less of a circus. The gates have been removed from the Ring of Valor, allowing players to engage as soon as the problematic elevators hit the arena floor. The moving pillars were adjusted to start the match in the elevated position, whereas they used to rise a few seconds after the match started. Most importantly, the damage from the flame wall was changed to break certain effects such as Fears and Roots after a certain amount of damage has been dealt. The last change is nice, but it's still problematic. The only thing that should damage another player in an Arena is another player.
