Except most support skills will be JP Up, and Magic is pretty useless until you learn the math skills so your stuck using half of the classes cause the other two thirds requires more work than a simple Monk/Squire set can't remedy. Not to mention that most of the movement skills are just fluff, and the best counter moves are Auto-Potion (using Hi-potions or X-potions of course) and the monks Counter skill cause its the most flexible counter skill. Ninja's have such an unbalanced stat growth that there really is no reason not to just make a party of them. Hell all you really need is the Chemist, Knight, Monk, and Ninja class and your set. Magic isn't practical and even though the Calculator makes it less tedious, you still have to go about the task of unlocking the class and then learning most of the top spells in the game to make any use of it and that's way more time consuming than just unlocking ninja, giving him Excalibur and just let them loose on the battle field.

I'm not even going to bring up the Special classes for the story characters, of which most of them are overpowered and makes using the basic classes look like a silly diversion for the player until the "real" party members show up. I don't mean to knock Tactics, I'm just stating that getting into a rut about character set-up is not unique to FFV and Tactics can easily fall into this trapping as well.

My point is that the systems are only limited by the imagination and will power of the player. If you think one set-up is too perfect, then of course you'll never be able to see the other set-ups cause you've already convinced yourself this is the right way. I genuinely feel that about a third of the way into the game, your mages have enough MP to be able to safely use MP as they wish in regular dungeons, so having the Barehanded ability is kind of a moot point cause my mages can destroy whole groups with a Level 2 Elemental spell rather than take the time to have each character attack. Its not like FFV dungeons are the long crawl that FFIV had, nor ethers are the rare item they use to be.
