Since I've noticed on my inf there is basically no groups that will take an inf in the RVR bg for keep takes could something be done that helps this. I was thinking along the lines of stealthers addin more ram damage or something
Think assassins have two roles in a BG: 1) clear the walls and 2) cut off solo reinforcements en route to the defend. The first is can get assassins into groups in Mid BGs anyway, although you don't really need to be in a group to do this, especially if vanish is up.
I don't think there's much else that would get you grouped in BGs. Even on Live, when group stealth was added through MLs, that wasn't really a big enough draw to make assassins a group class, and I sure as hell don't want to see that ability come here or anything more powerful than that.
