Obviously you don't have a single clue what you're talking about. Compared to any of the bands/groups you mention there's the vast difference that Bon Jovi is as much Jon & Richie as The Beatles were Lennon & McCartney, Aerosmith is Tyler & Perry, GnR were Axl & Slash, U2 are Bono & The Edge, and Rolling Stones are Mick & Keith.

Bon Jovi without their core members (Alec excluded cause he barely played on any record from the get-go) is no Bon Jovi. In all honesty, they should have called it quits after the Circle Tour. That would at least have been a fairly grand exit. Now it's just painfully excruciating watching what have become of musical legends.

In short; if you can't do it anymore, just don't do it.
