In HoH you can kill the mobs closest to the zone in. Easy to split em and plenty of mobs to kill.
In PoV the outer cave camp is the best for a kiter. Think there were only one or two mobs you actually had to worry about splitting. They seemed to resist snare a bit more so don't be affraid to tag pull with your pet once in a while. Just be sure to get em off Jaboner quick like or he'll be toasted toads.
Nobles Causeway is doable also. There are numerous places to setup a camp in that zone and you could probabaly get a pick up kiter group going as there always seems to be necros and druids there.
PoD you used to be able to kill just about anything, I *think*. But from other people's comments it seems they changed a few things and more mobs summon there these days.
Nadox might also be a good zone for ya. I spent many an hour roaming thru that zone solo.
