Very true. Just remember all the other bands that have broken up, and eventually reunited.
...and the list goes on.
Then there's all the celebrities that left whatever they did, like how Hulk Hogan retired from professional wrestling forever in 1994. Things change over time. Sometimes for the better, other times for the worse, but celebrate the good times, and hope that someday it will all work out so that Creed can go on the road again... someday.
