No Rooks on Dire Marsh Night

I have seen a total of 1 rook on dire marsh night. I think something is seriously wrong with the incentive structure for rooking into that map. It makes the map a bit dull because in the sponsored survival mode you basically get to run around the map uncontested and get 10k worth of loot. Likewise, I see no reason to choose rook over a sponsored normal run because we can coordinate better can complete objectives on the map faster.

Maybe they need to add more events that can only be accomplished by rooks or with the help of rooks? Maybe Rooks spawn with a clearance card to get immediate access to complex?
