Adding new dinos (or wyverns, or critters in general) would not be boring. Crafting creatures isn't as satisfying as taming or breeding for new stats. Was disappointed that the only new creature in Valguero was the deinonychus. While cool, I was looking forward to taming some other creatures, or to have access to rock drakes on more than one map perhaps. I'd heard rumors of a forest dragon, or a water dragon before it came out. Also that some of the other creatures from pc mods might make an appearance, for example that giant crocodile one I forget the name of (not the Sarco, obviously).
Searching the new map for as yet undiscovered creature spawns and being the first or one of the first to have new creatures is the best part of the game.
