Well crap.

It was just a fabulous unexpected gift to find that quests could be completed in raid groups in WoD. Made the leveling up process so much quicker for my ten man teams. I had some thought that guilds might start to abuse this by running 30-man level up raids and just completely destroying quests in a huge mob of toons, but figured it would take way too much coordination to ensure everyone could stay on the same quest, no one fell behind, etc. Maybe that was happening and drove Blizzard to revert this.

Anyway, this is a big motivation to do some quick leveling for those of us with more than 5 accounts and more toons we would like to have at 100.

So thanks for the head's up, ebony!
