one area wilds fucked up was in choosing to entirely redo animations for basic player actions like running/attacks and models for armor/weapons and monsters that already appeared in world (eg. wyvern jawblade, rathian, rathalos, etc). There's minimal visual differences despite the massive polygon increases, which underlines to me that the time spent modeling all these assets out from scratch would have been better served just importing the models from world and maybe touching up the textures slightly while they could work on other stuff. MH7 would be better off simply taking the majority of Wilds' current roster and tech as a baseline than it would trying to reinvent the wheel again for next to no returns.
