Lcea - Northwest part of the Yeti caves. Quite a few safe spots in the caves between rooms with no roamers and no Matriarch placeholders nearby. Spider caves can also be good if you can handle those and get your party to the back areas. While there are PH in there, the fast repop, see-invis and tougher mobs will keep most nosey people away.
Scorched Woods - North of the mine/meteor pit there are some mixed undead/fire mob camps that don't have any PH. It's near a Plaugebringer spawn though and in the middle of zone, so you'll have people going by. There are also some giant/mixed mob-type/no ph camps along the west side of zone, but I found the roamers/pathing/wurms to make many of those unsafe or wipes if you're trying to recover. Sarnaks south of the fort area by Chardok also have no PH, they do in the fort. Again, kind of busy as it's on the way to zone and part of the EoK quest line.
FM - There are a few no-named camps in the south and northeast, though other than goblins I didn't find any to be great camps. I pretty much avoid FM unless I'm doing a hunter.
Gates of Korsha - Along west wall, south of named chokdai spawn is a safe spot and you can set KA up to ignore the ph or pull bugs & such. The "portal" area to far east is also safe though part of EoK quest. One pather PH there along north wall.
OT - West lake, as mentioned above, is good if you put the rhino/cactus/bird ph's on ignore. Mid-south wall is also good if you ignore the stun bird's ph. There is another nice camp on the east wall about 75% of the way south. Can get one named pather, but you can ignore if you want. Also have to either have the faction or ability to handle the pather chodkai at these wall camps.
Any dungeon zone can work too, if you can get somewhere near the bottom or pretty far in. I'll try to camp a mage there for CoH or at least a spare rez/merc-rez toon,in case I lose the campfire.
