When I went there I was getting 1-2% per kill in AA, at 65 most stuff cons light blue, some green and a few blues, the blues are worth up to 2% AA the light blues are worth 1% and they drop some pretty good mid level gear, 45-50ish level stuff. There are two named mobs, one is a crawfish-man name Vinidi or somethign like that who drops a nice little ring that's 3 to all stats and like 45hp and mana, there's a named undead mob too, Telia something or other, drops some nice gear but both can drop a 20hp type 7 aug that is not LORE. Very nice, you could load up on those fairly easily I'd imagine, only seen one of the augs drop though.
The mobs here have FAR fewer hp than PoN mobs and seem to be comparable exp but they're spread out and there are lots of light blues making swarming at the stalkers still your best bet. BTW, I have gotten diamonds and blue diamonds from several of the mobs in the zone.
There is one danger, while you're kiting around there's a pretty good change the Cragbeast Queen will spawn. She's red to me, quads for 3800+ and has an AE Mana drain. I watcher her take down a raid of 18 PoT equipped toons... they got her to about 95% health before they wiped. She pops randomly on the islands so you might kiting a little cluster of light blue mobs when suddenly she summons and kills you in 2 hits.
