We have battle mentors, crafting mentors and gathering mentors. For all the hype they're putting behind the Feast, the omission of a PVP mentor surprised me.
Mentors can teach: class viability, rotation, strategy, assistance with decision making, when to be aggressive, when to be defensive and so forth. As we know, what applies in pve doesn't necessarily apply in pvp.
Plus, with the introduction of the Feast, I'm sure there are quite a few people who've never pvp'd before who're curious in trying it out.
Then again, the mentor system would probably be only good for the first 1-3 months or so before pvp dies down![]()
