We need a good coop mode

I really think AoE4 could use a good coop mode.

Straight up copying Starcraft 2 for this would be great.

In fact it doesn't even have to be as involved. We wouldn't really need different "commanders", we already have 16 factions. The factions themselves is enough variety.

It just needs some missions with varied objectives and a scaling difficulty level that adds randomized modifiers.

Who would play a mode like that regularly?
