I was reading through the first page and wondering why people were talking about with class bloat only in Ultimate Combat, then I saw that this thread had started three years ago.
That's somewhat mindblowing.
Just goes to show that no matter how FEW extra classes have been added in there'll always be someone declaring "Bloat", regardless of how justified it is.
In Paizo's case I don't believe that it's justified in the slightest, and clearly a lot of people above this post seem to agree with that assessment.
I just think it's great that if someone wanted to do an all-magic, all-divine, all-sneaky or all-warrior game then the players don't all have to choose from the same one or two classes, they'd have stacks of options so even games like those can have some variety.
