Make it less detail overloaded and complicated and more recognizeable by keeping it simple.
For example just two crossed swords but in bright blue?

This also makes it far better to display it at smaller scale

The icon used here is an example

I like the idea

I do what another icons. Both for the defensive, offensive and crowd control. Especially the cc,df,of frame needs to be looking abit more clean, maybe even add the buttons in the class icon frame

Just my thoughts here, maybe have one sword in blue (Alliance) and the other in red (Horde)?

yes but this is not the correct issue for that
here we only talk about the main addon icon
