When doing the storyline in Ul'dah depending on if you run off to level for awhile, unequip your armor before entering the fight at the Coliseum at the Gladiator's Guild. The battle you're pitted against is one you cannot win and there's no point in fighting as the skill-ups you receive will not be counted unless you can defeat the target. Unfortunately the game rigs this and you cannot defeat your opponent (It just sits there with a sliver of life left regardless how much damage you dish out.) so your options are to wait out the 5 minutes and take damage to your equipment or just allow yourself to be KO'd depending on your level. You'll save yourself the costs having to repair your weapon/armor so soon. Just a head's up.
