Stop even trying to tell us that Windsong / Elemental Force and green gems cost too much. Mastery on bracers is a fine alternative to Int/Agi/str, and it costs below 50 gold. There's always a cheap alternative, not wearing any gems or enchants is not the same thing as not wearing the absolutely best in slot enchant/gem.
On top of that, dailies do not only provide PvE exclusive rewards. They provide patterns, formulas, mounts and other vanity items. Why should PvP players not do dailies? All the hardcore PvPers I know are extremely keen on finishing as many dailies as possible each day.
