Instead of defending galv, go wait further south for the people who try to rush to FW. Kill them. Then once the pack of alliance comes who killed Galv, you kill as many as you can. Or you dodge them to keep your buffs. Then recap IB / TP towers and you bought your own offense a good time advantage. Combine that with trying to kill off as many alliance as you can and it's pretty darn hard to kill Drek with 2 Warmasters up.
