WA is quite complex so I might have missed the proper setting.
What is the enhancement in mind?
A) Interrupt able spells with spell description
---------------------------------------------------------
I want to see if a mob has a spell I can interrupt, whilst being notified what the mob is casting.
B) dispellable spells
-----------------------------
I want to see if there is a spell dispellable (on the target) and what I would affect.
These spells have subgroups.
B1) Mages spell steal
Where it is interesting what is spell stolen since the mage gets the buff.
B2) Magic
Priests
B3) Curses
Mages, Druids
B) Enrage
for Hunters, Rogues, Druids
How should it look and feel?
It should be somewhere in the drop downs and provide an option to use the spell description as text output in chat frame or on the screen.
