Ok, I have tried this place as a prot pally, and it was great, but I would assume that it would work for everyone. I also brought in a mage to help out, and we were making a killing, literally.
Anyway, in 2.3 they made a lot of changes in Dustwallow Marsh, and one of those changes was making the Theramore Deserters agro. These are the mobs that protect the tower for an alliance quest called "The Deserters". I am 99% sure it was called Lost Point, or Lost Tower, or something. Anyway, if you go to Theramore Deserter - NPCs - World of Warcraft you can look at the map, and see where it is. Don't mind the yellow dots over by Theramore, I am talking about the mass on the west side.
Anyway, when I went there to do my quest, I started to kill the now agro mobs. After about three had died, I started to get more and more adds, and I could not figure out why. The reason why, is that the respawn rate at this tower is insanely high. Now, this is always an AoE teams dream, but usually there are ranged mobs, healers, casters, and that sort of stuff around. Not here! Ther are all straight melee, with no real tricks. On top of that, they are all in a really small area, so you can go and grab 8-10 mobs VERY easily.
Even better, is that level 35 is about when prot pallies can start reliably using thier AoE skills, so this is the perfect time.
Anyway, the mobs inside the tower, the Lieutenants, were agro to me as an alliance character, but I was told that this was only because I had the quest to kill the mob inside the tower. Anyway, check it out for yourself, and tell me how you like it. Also, let me know if the mobs inside the tower are agro to you or not. I would assume that Blizzard will change the respawn times, since for most players, it makes the quest pretty much impossible to finish.
Thanks for reading, and enjoy!
