Think of comparing it to a mana regen based passive, Veigar's let's say. While fury is not an actual needed resource to cast abilities like mana is, they are both passives that increase the gain rate of their respective resource.

This is all irrelevant if the OP also believes Veigar doesn't have a passive either, but I think it's a fine passive on killer croc as it is.
