Divine Guardian - Invalid Target??

Hi Maintankadins!

Just a quick query. As the subject describes, I'm getting the Invalid Target error message occasionally during raids when attempting to cast Divine Guardian (raid wall). Does anyone know what's obstructing this effect?

Range. You're not close enough to the group.

Edit: It has a thirty yard range now.

Oh right,

Undocumented change...god damn you Tooltip!

Thanks for the info Nikachelle, I can now stop pondering this

The tooltip has said 30yards right from when it was changed.
It might not have been on the blizzard blues announcements but it wasnt one of the stealth nerfs.
And its never been usable without a group, not even back when you DID get the benefit from DG yourself.
