Oh, I have to pay him for it? Nevermind. I just wanted to be able to throw stuff at Aaron. I can do that out of PvP for free. Just wanted to expand my arsenal some.
That's some interesting stuff to know about PvP in general, though. WoW had its own special stat that was just for PvP (Resilience, I think?) back when I played. And PvP gear was the only place you could get it unless you ruined some PvE gear by socketing some meager Resilience gems into it. So a fully-geared PvEr with their PvE abilities will likely be able to hold their own against a fully-geared PvPer with PvP abilities? Or just at a slight disadvantage? I like the sound of that - makes the barrier of entry much lower for folks who might want to dip into the realm of PvP.
Or just want to enjoy the new Duel function.
Everyone has PvP actions. Someone who has leveled in PvP will only have those enhanced a bit, usually with a decreased cooldown or enhanced effect. If you're on a Warrior and Duel me, the only difference between us is that my PvP actions will be putting in a bit more work or get to be used more often, which isn't saying a lot considering that most PvP actions are on insane two and a half minute cooldowns anyways.
That said, the difference will shine through more in a 1v1 setting as opposed to say something like Feast where the game displays how woefully out of whack it's PvP ability design is. I still love you, Feast.
