There was originally a levelling system that allowed players to sacrifice their stats to restore their humanity. Each stat reduction would give the player four soft-Humanities each, with the limit being the base stats the player started the game with. The actual soul-level of the player does not reduce, possibly due to the system not being complete. However, the player could increase their stats without their soul-level increasing, up to the point of how many stat-levels they sacrificed. This would have made it a functional "Respec System", which would have allowed players to Reallocate their stats, albeit slowly.
