The Shieldwall Vindicators around that area put a self buff up called "Seal of Righteousness" which is spellstealable, AND stackable. It lasts a very long time so it will give you a nice window to stack 3-4 of them before taking on the rare spawn.
Once you got those buffs, head over to the rare spawn and just smack em around. They should drop very quickly and you should be able to loot your free 250 honor. All in time for your queue pop. As an added bonus, these spawns also drop Blood-Soaked Invitations for the brawlers guild!
Anyways, I know its not much but I hope you all enjoy!
