Your going to force me to wear PvP armour. Which is never better than raid gear, has usefull set bonuses for only 1 or 2 classes, and never gets updated with expansions. Indirect nerf to freeps. Make it a passive just like creeps.
No one's going to force you to wear it, but the defense bonuses of Moors armor via PvMP-only Audacity will make it viable without letting PvE-only players cry about needing to go to the Moors to get the "best" armour.
But since they're currently planning on capping Audacity at 7, I think they should go ahead and put it on jewelry as well, that way we have more options for capping out. Maybe gear that still requires rank could have more to higher-ranked freeps get even more flexibility as their reward.
