How about not adding a "Lot All" feature in the first place? I can't think of a situation in which a player would generally want to lot all items. This would be mostly to keep your inventory clean. The other suggestions are pretty good, even the "Always lot x item" would be nice for dynamis/limbus or something similar. Nothing in here (not even the "Lot All" feature) would encourage ninjalotting with one simple restriction: just don't make it lot anything that's currently in the pool, but only active on stuff that enters the pool. will give everyone enough to time lot, pass or kick possible lotting violators.
