Marshal- Tier 4. People seem to have a serious misunderstanding of this class. People often compare it to the bard (which is fair in a certain regard), but Inspire courage isn't really what the Marshal does. The Marshal can boost damage and accuracy a bit, but that isn't the only thing a marshal does. Marshals are much more notable for boosting skills & ability checks.
(Although in the right party master of tactics does let you rack up some serious bonus damage). Nearly every party would actually love to have the marshal, and the class isn't really ability score dependent (It just requires you to have a 16 Cha, albeit more is better). The Marshal has the unfortunate position of being functional but boring.
Expert- Tier 6. I love skills, but they don't make a good class. It had a place as a dip for skills in early 3.5 and maybe some strange Core + 1 book builds in modern days, but skills don't make a class not tier 6.
