Personally i would like to see it happen but i can understand it can take time to implement it.
What i'm interested in is what do u think would this benifit your mage experience?
Would this give you more room on your action bars?
Currently mage is the only class without that button style.
Other classes have an action bar similar why not utilse it?
We already have too many spells on our action bars much like priest and warlock.
better yet why not convert warlock and priest armor spells to the pally aura style button as well?
