Bank features a wide open space at the ground floor that is actually horrible for the defending team to defend because Glaz or anyone could snipe them out from the outside. For Hostage situations, it is better to hide the hostage in the Vault because it forces the attacking to be out in the open in both the hallway towards the vault and the railings.
The second floor is a deathtrap for the defenders too because the walls are just breachable. The good thing is, if defenders spread out across every room, and probably one of the defenders camp in the third floor to stall the breachers up, this should give a sizable advantage to them because of the countless opportunities of ambush. If it happens that the objective is in the second floor, never cluster up together.
The Fuze does wonders here too especially in the CEO area. The conference room can be cleared out with the cluster charge easily given its really small space. Pulse will have a field day because of the rooms.
