The worst part about it is the instant setup imo. It should require the building be occupied for at least 10 seconds for a set up.
Having literally never used it I kept wondering, when I faced it, why one second it wasn't there and the next it was. Is it really instant? That's mind-boggling. I know COH2 is not vCOH but in vCOH it took, what, 30 seconds? And it could be decapped. I seriously don't understand why it shouldn't a) take longer to set up and b) be decappable.
