Honestly, they could have just reversed the combo order of Overpower and Mythril Tempest. It's easier to hit all enemies with Overpower after you've gathered them. Even just changing the range to 180 degrees in front of you would have been very effective, while keeping the satisfaction of using the skill intact.

Circular Overpower is not a make or break change for WAR, but it isn't necessitated by anything either. It still sucks because it takes away how good it feels to use the skill. It's concerning because such changes are green-lighted when far more pressing matters aren't even addressed.

I would imagine physical ranged LBs being changed from column AoE to circular are coming up soon as well. Or did they change that too?
