Great news for players of all classes and levels (well, levels above 15)! In the latest official patch notes update for the Patch 3.3 PTR, Blizzard added the following line:

Meeting Stones: To use any Meeting Stone, it is only required that the character's minimum level be 15. There is no maximum character level requirement for any Meeting Stone.

Now that's a change that's been a long time coming. Ever tried to get your level 80 guildie to Deadmines to help you carve a bloody swath straight to Van Cleef? It's a pain! Ever tried to get your lowbie to a high-level zone without a portal? Also a pain! This completely removes the restrictions on using or activating summoning stones so long as you're above level 15.

Now you'll be able to bring whoever you want to any dungeon summoning stone with just two people. A fantastic quality-of-life change, very likely added to ensure that interest in rerolling remains steady until Cataclysm comes out, but who cares? I'll take it! Who wants to run me through ZF?
