The Infantry Problem 2

[Rezev]

I've got small idea how to make infantry usefull; brand new game mode where players are on huge open space map (no buildings at all) and they have to build base using different cades (platforms and heavy cades would finally find some use), this would be hardcore game mode as medic and ammo boxes would be crucial.
Let's say double-triple longer prep time before wave 1, different waves + maybe cav wave?; as Kaas already said siege wave where bots would focus on cades.
I guess that would be very hard to win but also very fun
