if you sort out your spells correctly on the action bar, you well be 100% better at pvp and pve.
sort from long casts down to the instant cast is best for mages.
what ever you do it would best if you use the action bar ups and down macro to make spells more easy, fast and efficent.
ActionButtonUp(buttonID);
ActionButtonDown(buttonID);
this could be used for many advantages. one of them is spell/melee. or it could be use for easy macro sequencing.
macro1, macro2, macro3, ActionButtonUp(2);
macro1, macro2, macro3, ActionButtonDown(1);
ect.
