What game modes do you think deserve a rework and what changes would you like to see in them?

I think that the Arena deserves a rework. Maybe if we could pick up certain power ups/upgrades every time we reach a milestone (kinda like the incursions), the arena could become a whole lot more fun. Also, since Kabam mentioned that they would try to add hazards such as spiked walls, I'd like to see something like that in the arena.

I want wars to be based off skill alone. They could be itemless and 2* only, and you had to play better to get better rewards
