Idea for a new Shadow Priest playstyle

[Dejiko]

Doing away with the active spell which brings you into Voidform, a new idea is that you would naturally go into voidform once
you reach a certain insanity threshold.
Void Bolt is a spell that becomes active once you transition into Voidform.
Removing Shadow Word: Void, you now have two charges of Mind Blast baseline.

Upon reaching say 60 Insanity you transition into Voidform without having to cast anything, you are simply empowered from
having casted a number of spells, the effect of Voidform could be altered numerically of course.
Once you`ve reached the necessary amount of Insanity to transition into Voidform it begins to slowly decay at an increased rate.

The talent Legacy of the Void could be changed to offer a cast time reduction on your spells based on your current
amount of Insanity.

I like that better. Insanity isn't something you can control, having it build up inside you and release as you deal out damage after it takes you...I bet that would feel better.
