its not unrealistic to beat someone 2v1, the pvp side will have more skilled players than your basic pve person, thats not always true as some great players hate pvp, but pvp is geared toward twich players who react fast. I myself am always deverting shield power to whatever side im being attacked from, i noticed ALOT of pvpers do not do this and usually die every easily while i live even in 2v1 sisuations. Lets not cry nerf so early till we learn the game.
