I too have no interest in pvp, that said I have to say that so far my reroll on KJ isn't bad, I am leveling as a group versus some twinking or boosting there, two groups of 5. While I would normally do a whole lot more questing there is little real difference.

I started out on pvp server and I really wasn't fun (though it was my first 60 and i was holy priest), I have to say it was much worse than this on many levels (real boat camping jerks). With the dungeon queue and the Dal portals, epic mounts its not a big deal. While a simple holy nova spamming priest can decimate my guys now, much less a attack from fan of knives, shadowfur, living bomb, etc ... (yeah that is pretty cool to one shot 5guys ... once) soon that will change a bit.

Maybe once a day I get camped hard and about twice a day I get beat up a bit. Sometimes I run into someone my level that is questing and they attack me solo, I have no idea wtf is going on with those people. Other than people that attack me I leave folks alone.

I am sure crafting and various achievements are issues, I won't get getting Nether drakes on these characters for example. And it seems a lot of the encounters with 80s I run into are people likely on mining routes.
