Well, I finally got my 5 posts. This has probably been reposted alot but I couldnt find anything .
Last night, I finished my AB daily several hours before the dailies reset. When they finally did reset, I was next to the BG daily quest giver. Boy was I disappointed when I got AB for the second time in a row.
About 30mins later my friend called me an idiot for crying over getting AB again; It was the AV daily!
There seems to be a delay, on my server at least between when the dailies reset, and when the alternating dailies change. Im going to try this again tonight since I have my juicy AV daily.
This might work on Heroic Dailies too, but I dont do them enough to get an idea.
