I tried it on Tribble
Maco and 2 pc borg is very weak compared to before. The borg shield proc was pretty large for an escort's healing ability, a cruiser can get away with it but escorts can't use this for anything but brief combat.
An example is the tholian red alerts, your shields will drop fairly fast with the maco and 2 pc borg, but with 3 pc borg I can keep them up for quiet some time. An escort isn't going to last 50 hull hits for the very rare 2% hull heal proc.
I'm toying around with the full M.A.C.O. set with the borg console and the 360 degree borg cutting beam. I've always wanted a full range beam weapon, I'm more courious as to how well the cutting beam works, and how well the 2 seperate set bonuses will work together.
