I don't like this debuff idea. Its like inspect you can't turn off. Except it'll get people killed. Particuarly the people that already hate PVP to death and are merely forced to do it because its the only efficient way to get VP. (And it's only efficient for 2 out of the 9ish battlestations, and only for about a third of the 24 hours that make up a day.)
This is going to be like torture to those lesser PVPers, who I definitely count myself amongst. Would rather stuff kerosine into my veins and set myself on fire from the inside out than actually do the battlestations for more than 15 minutes at a time. But that's another issue for another thread.
I do think this feature would be nifty for PVM. But for the PVP, it's just going to be a new way to rail the bottom end of PVPers, be it in skill/interest/timeserved, it's going to mess with them all. Perhaps it has its place in duels. In fact, it totally does. All for seeing this happen for duels. But for flagged/unflagged brawling, please god no.
