Anyone saying the Hyuuga's arsenal isn't limited probably hasn't watched shippuden or read part II of Naruto. The Hyuuga became as irrelevant as the akamichi clan. The Uchiha clan and Hyuuga were neck and neck in part I and could be seen as rival ocular abilities, but then Sharingan got more sophisicated. We got Mangekyo sharingan, we have eternal mangekyo sharingan, we have susanoo, different ms abilities (time and space manipulation, inexhaustible black fire, mental persuasion). Don't get me started on Izanami, and Izanagi.
The Hyuuga were stuck with there 359 degree vision, x-ray vision, and there palm techniques and shit. No Byakugan variation, so special abilities, no manifesting godly exoskeletons, etc. Weaaak af.
Still way better than punching the ground and healing really good.
