Velociraptor used to hunt in packs. Using a solo velociraptor in battle is weak and very vulnerable. May I suggest that Velociraptor could start hunting in groups of two or more when they reach a high enough level? For example, a level 30 Velociraptor could hunt/battle with a second velociraptor. If both Velociraptor reach level 30 they could hunt/battle with a third velociraptor.
