Tanaan Jungle

[MultiBear]

Was thinking of putting a Lock or Disco Priest with the Hunters to mix it up a bit.

Sounds like a solid plan, I don't see any reason why that wouldn't work like a charm. Having one or more pets tank at range is a big plus and means most mechanics won't bother you much.

Only real thing that comes to mind atm is to be aware of what the green fel sludge does that you can find around the Throne of Kil'Jaeden: for every second you spend in there, characters (and pets) get a stacking debuff that makes you do 10% more damage, but also take 10% more damage (per stack), and 10 stacks will kill immediately. If your pets end up in there a few times, they'll become rather fragile - just something to be aware of.
