I'd suggest an Illusion controller. It's relaxed play (except with kin as a secondary), but still powerful.
You send Phantom Army out to take an alpha or just add dps. Phantasm floats behind your shoulder and rarely causes headaches. Your attack chain is basically two powers, Blind and Spectral Wounds, along with strategic use of deceive. Add one of the invis powers and you can stealth anytime you like and eliminate the chance of aggroing before you're ready.
