Imo, a really cool gamemode would be to have an ability select screen instead of agent select. Wherein for each ability slot, you choose an ability from any agent that normally goes into that slot.

For example, you could choose to have a combination of Sova's drone in slot 1, skye's tiger in slot 2, Omen's smokes for the signature ability, and Phoenix's ult for your ult. This works because sova's drone and skye's tiger are normally activated with different buttons.

Additionally, each ability can only be picked once per team so we dont have any duplicate ability combos.

Or perhaps, if there are too many options for each ability. It could instead show you a random selection of 3 or 4 abilities for each slot to pick from.

Personally, I'm dying to have a gamemode where we can mix and match agent abilities. What do you all think?
