I made one and have it to Level 30 something right now. Psi / Ninja. Took stealth and all of the placates (Placate from psi, pacify, smoke flash, and misdirection - mostly as a trial). With placate you can still get your AS in first strike, and with Stealth + Celerity +Stealth on Sprint you still get enough stealth radius to sneak up to just about anything. Once Mids is updated and I've figured out if all the placates are unnecessary I will make a real build for it, but it's been a lot of fun to play so far (all solo / ToT). I'm sure it's a terrible group toon.
