Creative differences like when lead singers leave popular bands to go solo or do side-projects.
Like when Bruce Dickinson and Rob Halford left their respective bands for solo projects. I think Maiden and Priest should put music for those bands on hold until Bruce and Rob were ready to come back. In the meantime, the rest of Priest and Maiden could've equally done solo or side-projects. Unless they parted ways on bad terms...
Like Metallica did with Dave Mustaine. Having heard both sides of that story, kicking Mustaine out while Lars, James and Kirk were getting shit-faced almost every gig, was hypocritical and unfair. They should've all went to rehab and sorted themselves out.
