I'm taking a wild guess here, this is untested, so if you think I'm wrong please do call the BS-flag on me:
To be flagged as support I think you must either a) have some points in a healing soul in the spec or b) be quite deep into justi.
You need 22 or 24 pts in justicar, no way around it. Which is really silly IMO.
If you have a tank build as one of your roles, you don't need any more than 11 points in justi in order to have a support spec (Inquisicar at least). While putting more in justi for Righteous Mandate is nice, it's not really needed for 5 mans anymore due to the T1/T2 nerfs. DoL spam and Healing Breath (w/ mouseover macro) is pretty much all thats needed anymore.
Unfortunately, if you don't have a tank spec, you're stuck putting more points into justi which will kind of be a waste of points outside of a shamicar build, which can still provide decent support in T1/T2 runs.
