I remember having a rough time getting through Wizards. The animation looked good but at some point it looked like they ran out of money. Sort of the same problem with Rock and Rule.
I think they did on Wizards. Or at least didn't have enough to do what Bakshi wanted, so he just used old stock war footage. Rock and Rule, as I said, was more of a lack of direction than money as they did some pretty cool optical effects and the production quality never seemed to suffer. It just seems to be a film that never stopped evolving. It was originally a kids film that morphed into an adult film that didn't seem to know fully what it was doing.
