Out of Party Leveling not able to anymore?

[Gares]

it looks like this wasn't broken to me.
I tried it last night and got the xp I was expecting.

I think you just had your level 80's hitting targets to low or you used pets ( and totems are pets )
you need 72+ preferably level 73+ if you are going to use level 80's to help.

Alright so I ended up at the Onslaught Camps in Dragonblight yesterday. The mobs are mostly level 72-73, along with the mobs in Carrion Fields. I was able to boost my DK from just making 71 to 72.5 in the matter of 3 hours just grinding down the 5 camps and going into the fields for a few round up pulls (mobs are same level) and then going back to the camps.

As someone stated earlier, as long as the mob is Green to the 80 (which is level 72) the tagger will get full xp. If its anything lower 71- its based on percentage of damage dealt.

I think I am going to stay here till at least 74, and then I am not sure where I will move to because I know at 77 I will hit the elite skeletons in Icecrown, but in between I am not sure of.

As for the place in Zul'Drak its the Altar of Qual something. Now when you first go there the elites are all around, but when you complete some quests and head into that part of the zone you phase out of your body and there are no longer elites there.
