Just to plug for survival - It's nice to be able to up yout parry chance/immobilize melee folks in addition to good traps that you can drop twice in a row if you need to.
It's also nice to be able to put a 12 second sleep on anyone at range (again, twice if readiness is up.
I would reccomend SV/MM personally. It's fun once you get used to it, and also good for raiding.
Edit - sorry, here's me/my build
