using weak auras to create a gif-like status bar that only works for certain specs
 

sorry for the title :D

I got the texture for status bar. it's circle shaped (like diablo 3 orbs), so I want to it to be vertical. what I meant by gif-like is I want the status bar to keep "rotating" indefinitely, like a gif image. I also want it to activate only for certain specs, specs that use mana as their primary resource (for example arcane mage, resto druid and holy priest, but NOT shadow priest, balance druid or other specs that use mana as their second resource). hope I explained myself clearly, I know it's a complicated but I tried my best. :o:o
