Paladin at level 24 - Where to go?

[Sajan]

Warslik's Wood is my favorite laid back 20-30 leveling zone. This area lacks undead, but it's severely underused and stress-free.

20-24 - Iksar Bandit Camps scattered through the zone
25-30 - Brute Caves right outside Dalnir
25-30 (Alternative) - Solo/Duo the Giant Fort

If Kunark isn't your thing, I would try to make your own groups in Upper Guk and take advantage of that big ZEM. There have been quite a few players taking this leveling path lately so there's a decent amount of people to form a party with. Oasis is nearby to poach replacements from whenever the time comes. South Karana has been another one of my favorite laid back places to level. The Aviak village is dripping with nostalgia and decent exp!
