Well, i know i've personally trained 4 Boffs of friends in EWP3 this week alone. Feel the burn Feds!
I've noticed some klinks spewing warp plasma out of their BoPs lately. Silly people, hazard emitters and any engine boost will get your ship right out of it. It's really only a tool cruisers should be using to protect their hindparts. Trying to stick an escort with it is generally going to be FAIL.
Actually, the fact that the BoP can run circles around you makes it an incredibly effective tactic. Couple that with a SNB, Tractor Beam, PSW or some other kind of disable and it's really bad news.
On a semirelated note, I understand that there is a doff which adds a chance for Warp Plasma to disable you. The way Warp Plasma has been acting lately I'm concerned that maybe some part of that has slipped through somehow. I really do think something is fishy about this skill right now.
