Pathfinder Tiers (Once Again)

[Bhaakon]

Gunslinger; Gunslingers are probably high tier 4, or low tier 3, though an optimized one could hit mid tier 3, it would require a little work.
Also the pistolero, and mysterious stranger archetypes help it out as well, helping it reach mid or high tier three with less optimization(as both dex and charisma are useful for non-combat skills). edit; Also one somewhat useful ability for gunslingers is that both mysterious stranger and pistolero can be taken at the same time(at least as far as I can tell)

Monk; As has been said, some of the recent ultimate combat monk changes could help boost it's tier as well, though standard(no alternate class features/archetypes) PF monk is still probably high tier 5/low tier 4 at best.[/SIZE]

I've got to believe that's going to be fixed in a FAQ or errata. It's blindingly obvious (to me, at least) that pistol training was supposed to replace gun training.
