WowAce

Wow version, Retail + Mists of Pandaria (tested both).

Class -> Feral i.e. melee class

Examples of bug,

Tiger's fury randmoly and not always will go fully red, and this ability specifically shouldn't go out of range at all, its an instant ability for the player.

Swipe on Retail goes fully red even though I am on melee ranged while other abilities remain normal.

Other abilities also go fully red (some of which are buffs just like tiger's fury).

I have been getting this as well since 12.1.5.  If you target something out of range while out of combat then get in range of the target, all your abilities still show out of range until you retarget the target.
