The originals... ok, not exactly, but the original named "The TransFormers" anyway. Take THAT, Diaclone! Generation 1, Generation 2 - Removable fists? Check. Unlicensed vehicle modes? Check. Kickass tape deck robot with transforming cassette minions? DOUBLE CHECK!!!
With TFs, I generally consider "incomplete" to be about the same as "broken". And, a missing piece is a missing piece, so yes, I do take off points for that sort of thing, even if it is a piece I do not especially like. If nothing else, having integrated parts can help avoid missing pieces.
