Best Reasons NOT to Gish

Yeah, I was thinking more like a little utility casting for times when the party is split up. Not something that'll come up much, but the difference between BAB +20 and BAB +19 doesn't come up much either. And since this is likely non-combat stuff, it works for a rager too.

Although, there is Mage Slayer and the related feats. Taking those is going to crash your CL enough that a dip no longer gives casting, and they're pretty good feats (depending on the campaign, but if we're assuming high-op then likely applicable).
