PvP Class roles/playstyles

[Master Roshi]

For a new/prospective player, if you choose a class, what are you looking at dealing with? Are there 5 million Shammy/Mnk duo's like on Blue?

Figured the red vets could weigh in on some class info:

ie:
Monk
playstyle: burst dps?

Pros/cons: curse of being kited for life, can innate fear?

etc.

Any info would be great, and possibly help others join.
