or doing hard mode for those elite tomes while he's at it

My bet's on the elite tomes, most easily farmed greens are in the can. Some greens are still worth farming, but some bosses are so easy to farm for elites that it's a better use of one's time.

Probably Elite Tomes, Monk or Ritualist ones I believe. Their prices seem to be slightly higher than the others.
