My bard, I often run back to PoK. Easy to grab buffs before heading out for the evening next time I log in. Back when I was farming Nadox, I usually camped out in Gunthak after selling and banking.
My rogue is camped in Butcherblock at the Wayfarer camp. Since I've mainly been doing LDoNs, there's no reason to keep hiking back and forth from PoK. Now and then I stop off in Kelethin to bank. Once I hit 46, I'll hit up PoK to train and stuff.
My mage is camped in Jaggedpine Forest waiting on the potameid queen to drop the Defender of the River already instead of gimp cloaks, crowns and nullify magic wands. I'd settle for the +7 INT leggings.
My Shadowknight is camped in Shadowrest, waiting on her lost corpse to become summonable after it sank through the floor of Padual. Yay, collision system!
