Whats weird about saying that? Some bands have great frontmen, some dont. You rarely hear from the other members, thus making him the centerpiece of the band. He tends to ramble on alot...at times hes come off as racist (revival tour talking about a sister and doing a schuckin n jivin impression of a black woman).
I think the term's weird to use when not talking about him actually fronting the band. From a "when he's playing / fronting the ban" -- don't know how anyone could say he's not one of the best in the game right now. I know he's the centerpiece of the band ... don't really get what your issues with him are though. That he rambles? Haha, whatever. Just seem to pick some weird qualities to declare him your least favorite frontman.
I mean, we got frontmen stealing from their fans ... but hey, at least they're not "aww schucks" ...amirite?
