I've stuck my fingers in my ears over this whole issue, to be honest. I've decided that if a monster can be found in an area, it has always been possible to find it there, regardless of whether the game at the time allowed for it. What this really messes up is the Geography of Monster Hunter world, because they're now being very selective about which monsters have made it from 2nd Gen Areas to 3rd Gen Areas. Plus the amount of shared monsters suggests the two sets of areas are much closer than originally thought.

Anyway, Plesioth or Lagiacrus as the top predator around the D. Islands? They both fill a similar ecological niche, after all.
