yeah expertise is more an OS-1 card because of the inherent action inefficiency of the title, while the XG-1 has linked batteries to compensate and can therefore supplement their offense with crackshot
as for the XG-1 SLAM benefit, yeah I don't think it does enough to merit building into either. If Jamming beam did any damage, though...of just imagine the possibilities!
T-beam might be okay, though, but then you have to put predator or expertise in the ept slot just to hit anything. You could ASLAM, but ASLAM does nothing when you want to fire your > 2 points cannon
