My Warrior is currently lvl 73, and I have been using s/s from the beginning. I only do PvE; I have no interest in any form of PvP. I actually use a hybrid build of sword/axe, and then the weapon swap is main hand blank/sword (this in the H screen where you are setting up your armor and weapons). So when I fight, I am either sword/sword or sword/axe. If I am fighting 1v1, I start off with Impale, then Riposte. This really gets the bleeds going (be sure to get the Deep Cuts trait in Precision). If I am attacking multiple enemies, I start with s/s and Impale (it is a ranged attack), then I switch to sword/axe for the offhand axe attacks of Dual Strike and Whirling Axe. I slot Signet of Fury to keep my adrenalin full, and burst attack as often as I can. I will flip back and forth between s/s and s/a during the fight, so I always have an offhand attack available. This also helps me keep the bleeds going.
BTW, if I know that I might need a ranged weapon, like in a zerg, I will substitute my rifle for my offhand sword, as there will be so many people stacking bleeds, that I would rather have the raw damage of the offhand axe.
Hope this helps.
