I've resumed playing after about a year (or more), and it seens the nerfs to the Mesmer have piled up; I've been wondering: is the class still useful as support? I've built myself a Diviner (pwr, crit, fer, boon) on a whim back then, and it seens that it has no place anymore. HB or Rev does everything better. Is it still useful, at the very least, as an alacrity support? What gear (besides zerker) should I bring so that I'm useful to a party?
