This is a list of various "extra information" about the upcoming 1.5 patch off the World of Warcraft forums.
Cloth Donation patch allows players to gain reputation, allowing you to raise your faction to exaulted with various other factions using a fairly simple repeatable quests. (Sucks to be a tailor, though.)
Auto-Taunt for hunter pets is now broken.
Nightfall (Warlock talent) no longer procs.
I'll add more later.
Note: links to official forum removed, as they have been pruned.
