theres 3 camps and 154 people in the dunes. Same for all the leveling spots. You have to cut eachothers throats for exp on this server. blame nasomi for not fixing broken mob TP moves.
this is kind of the lazy stance, fwiw.
If you are mad that all the camps are taken, go XP somewhere else. Holding multiple mobs in the dunes will always be a bit of a d move. If you have a PL, and want to pull very quickly and have them overlap a bit at the end of each fight, then go for it. If you want to grab them all as soon as they spawn and just have your PL hold the hate? It's not against the rules... It's just going to make people judge you. Only you can decide if that's worth it.
As D said, there's plenty of places to go though.... ESPECIALLY if you have a PL, and thus aren't new. The dunes isn't the best place to XP, it's the most convenient. If you are the person with the PL, make your party and go somewhere better.
