Lightning damage is already potent on its own, this function of Thunder Hooves makes it almost required for any build revolving around dealing lightning damage, and makes said builds even more overbearing in that now they get free movement on top of the heavy critical damage they tend to deal.

Forcing Thunder Hooves to only gain charges via movement makes it much less likely to give the user a huge momentum gain over their opponent, seeing as right now they get free moves just for hitting people as they normally would.
