I recently faction transferred from Alliance -> Horde (first time Horde ever..) and ugh! My Argent Squire and Alliance Balloon naturally didn't transfer over, but I didn't think getting them back would be such a headache!
The quest giver for the Horde balloon had no quest for me and since I already have the "Exalted Argent Champion.." achievement (exalted with all the factions), the Horde factions had no quests for me either.
I've submitted 5 tickets already and these Blizzard GMs are just copy/pasting responses, they're not even reading my tickets where I've specifically stated that I can't do the quests again since they're not available for me.. arrrghhhhh.
Really frustrated. Sorry about the rant
