The onslaught camp is a really nice spot to aoe grind. There are 5 large camps close to each other. And like a previous post sugested, by the time you complete the 5th camp the 1st camp will have allready spawned.

The Venture Co. mobs by the Suntouch Pillar(or where ever) seemed alot more spread out and they didnt give too much more xp compared to the onslaughtcamp. Anyone else find a good ginding spot around lvl 76?
