Decent players will smoke you but in certain situations it’s great. I’ve planted C4 on both containers in terminal and then run up to the balcony to mow people down in the confusion.
Usually it’s a suicide mission, i know i’m going to get killed up there, the real question is how many people do I take with me?
Also on Dome I will guard the one way with the double wall jump and then if the other side needs help I can hop on the MG to suppress a little and quickly hop back off.
I think the real mistake is that some people will just straight camp on the MG which is not good.
