Hey All,
I'm sure someone here has the answer for this. I looked around the net but it appears I couldn't phrase my question correctly because I couldn't find and an answer.

How does WoW order your group?

From experimenting it appears that its not:
A) by level
B) alphabetically
C) by class
D) by time joined

knowing in advance how my group will be ordered will help my macros. I know you can use pitbull to make it appear alphabetical.

After a week of casual playing, my 1st multiboxing attempt of 5 Druids is now at level 23 and have finished WC and RFC.
I'm enjoying it so far. Thanks for all the info on these forums.
