I'm not sure what my win % is, but lately I cant recall losing in WSG very often. I keep a very simple strategy (kinda like littleburst).

-Before bg starts, I ask the group if they don't mind me carrying the flag so I can protect it.

-Go get flag and on my way back blow up alliance carrier (Frozen Power on main is great for this situation, then blow cooldown usually kills them real quick)

-If he gets away, I go to the roof and ask the rest of the team to come get flag and defend it while I go get ours.

I know rated bgs would be alot more difficult but if this strategy works, I don't see y 2 boxers cannot do WSG and win. I truly believe the way things are now (against random teams), if i had another decent boxer playing with me, we would be able to farm WSG for rep or whatever.
