A great big pile of info about future patches
Schwick, a community MVP on the European forums, took the trouble of compiling all known info about future patches into one handy thread. The highlights include:
Druids will get an epic flight form, but they'll have to have 300 riding skill to use it -- unlike their regular flight form.
The priest spell Circle of Healing is still being looked at for changes, but Blizzard doesn't anticipate changing Pain Suppression in any meaningful way.
The PVP matching system will be introduced in the next content patch.
There will probably be an Emerald Dream dungeon, but there's a good chance it will be saved until the next expansion. Ravenholdt and the Sunwell will probably be important in the future.
Professions will be getting a revamp, and engineering is the first one they're going to look at.
Warlock and hunter pets will be dismissed upon flying, so they no longer drag behind you on the ground and make you feel guilty.
Guild housing, player last names, and guild banks are all things Blizzard is currently working on.
Thanks to Chris for the tip!
