Choosing a t4 main. [Sorc, BG. or WE]

[lalira]

So i know people tell me play what I like, and I enjoy all three of the classes to the point i have trouble deciding what i want to main between the 3. I've gotten my WE to t4, and sorc and BG are both about to hit t4 also. Can I get some constructive advice of what to expect between the three classes? I mostly want to be helpful, that being said I enjoy 2h BG and switch to SnB when I need to (aka lack a real front line) though reading the forums i cant find a solid build or guide for them.
In short im looking for what each can bring to the table in t4 Pros and cons and what destro needs atm.
