^Who, John Harrison?
I vote Sela, even if just to be one of the Rommies killed in NEM (it would have been a nice way of getting all the original TNG cast back onscreen for their last outing), while Tomalak could have been on Donatra's ship.
I don't particularly care for Lore but he might have made more sense in NEM than B/4.
Kang, Koloth or Kor ought to have been in TUC and/ or TSFS.
