Grinder's Planes of Pains No quests, all grinding and camping, think original Luclin shards x 100 1 zone Relatively fast repop so you plow to camp site or through zone to teleport pad where it zones you back to starting point and now all mobs are +1 level including named, loot adjusted accordingly, repeat as many times as you can before wiping...
I think we could probably get 2 more xpacs out of this theme as we work to dial it in. "The Jacket-Weather Lands" "The My-AC-Stopped-Working-And-The-AC-Guy-Cant-Take-A-Look-At-It-Until-Tomorrow" Lands THEN "The Just Right Lands"
The Frozen Garden - even tho PoG probably has nothing to do with this coming expansion... Still hoping to see a little bit more of Tunare.
