It's nice to be the one who stays current and make commentary at those who aren't where you are.

That kind of elitism baffles me.

PvP and PvE rotations are mutually exclusive, you don't have to learn one to learn another. And if they're learning, then they're learning. This game does not put empasis on heated competition in PvP. It's not a PvP-centric game. But if they're making an effor to learn it PvP as they go along, who are you to dictate how they should advance their character after reaching fifty? Frontlines provides a good alternative to Pre grinding and it begins to teach you the importance of teamwork to boot. I'd say it's much better training than sitting there repeating the same easy mobs over and over again being carried by a bunch of people who are either Spirit bonding or going for quick tomes.

Again, I advanced Paladin through PvP on a brand new character. Perhaps they're trying to do the same? Try not to look down on people so hard, it'll give you a creek in the neck.
