im usin a R50 2H and R50 GUN, they increase my dps with 500/600 then the HK 2h and bow i had so yes i am using them, and at end i still have 435HIT with 2pieces of PVP on (and i am top dps or very close depends encounter in my guild)
As long as you have the HIT who cares i strife to be the best and if that means having to wear weapons from pvp to bet it then sure as hell i will use them, same for the conquest trinket it rocks
It's still ok at the lower end of the pvp rank gear too. PvP is decent gear for the most part.
My alt levelled through pvp, so when he hit 50 I got some crafted pieces where I could and used pvp gear in the other slots. For dps, healing and tanking. As long as you have the hit/focus/toughness - which is very easy to get from crafted gear - it's much better than greens or blues.
