No, your absolutely right, I gear to compensate for dexterity. Honestly I just had my shoulder replaced have to mouse with a cutting board in my lap. Im pretty proud of myself just to be able to parse green let alone work on 10 man hardmode progress with my guild. Also im commenting on bgs not arena. But even there, gear trumps skill, its only when you have homoginized pvp like fps games that have no caracter progression structure that dexterity becomes the primary deciding factor.
