If I have GG or arcblade I generally pop it. With arcblade I've actually had pretty good success just blinking close and hacking the shit outta them. I don't think they expect it as they are so used to people running away lol.
Look for death spam and if it's not someone on my team that popped it I either run, or if my bow is up and the hammer guy is near he gets a free tether..
This actually worked for me...he waved back and we started dancing...only for my team mate to kill him...and then SHE salutes me and walks away!
The second time I did this, it resulted in other team mates actually stopping and looking at us (we were still on opposite teams, mind you) and after about a minute both teams are dancing with each other at point B. [Best thing to ever happen]
[spoiler]until a dumbass striker titan joins in progress and kills the entire opposite team, thus ending that sacred bonding moment between opposing sides [/spoiler]
