this is excellent to know! thanks
for some reason I thought you had to finish something before they came available as dailies. I don't know how I missed that..
You need to defeat the Grand Master of a continent before the dailies for that continent unlock. Even for the lower level Tamer battles.
Example: If I want to battle the Tamer in Ashenvale everyday, I would need to defeat the Grand Master Tamer in Winterspring first. After that the daily in Ashenvale becomes available, as do all of the Kalimdor Tamer dailies.
That is, unless they changed it so the Tamer dailies unlock as soon as you complete the initial quest to defeat them?? Someone please correct me if I'm wrong.
