Would be awesome if there was a checkbox I can click that auto arranges the raid as people join. It would only last during "invite" phase.

@f90 any chance of this being implemented?

Interesting idea, I think that would be a cool feature. It would only be possible to activate that as raid leader so that we prevent the situation where two raid assistants have this feature turned on and constantly try to arrange the raid to different setups, so that they never end up finishing the rearrangement.

I think once I find some more time I will come around to implementing it. Probably a checkbox next to the rearrange button in the group window. Upon clicking it would deactivate the manual arrange button, and it would periodically fire off the rearrangement command (maybe every few seconds), as if you were constantly clicking on the rearrange button yourself.
