The Tigrex model in P3rd is in fact improved from its Unite one. But what i meant is that they probably didn't need to revamp it as drastically as Rathian and Rathalos. The problem with those two was that, basically, in older games they just didn't move like living creatures (look at them goddamit, their movements were so clunky and robotic), they had VERY cheap attacks (gonna attack the head LOL NO INSTACHARGE) and terrible hitboxes (tail spin over your head hitting you).

Diablos had its attack pattern changed and his movements improved, but you can see most of its animations are identical to those of Unite. Maybe that's why he was one of the hardest monsters in Tri. I'm glad they fixed the tail sweep, it was fucking ridiculous before.

Tigrex and Narga, by comparison, were much more fluid from the start and only needed fixed hitboxes and so. Many animations of Narga are shared by Barioth and i've never heard complaints about it.
