FFV is easily exploited with the right class combinations or even just individual classes (Samurai, Chemist, Beastmaster). There's a popular challenge run called Four Job Fiesta that limits you to one randomly chosen class per crystal that you have to stick to the entire game, using only those jobs and the abilities you can get from them, and all the weaker classes get to shine when you're locked to them.
Other anons have mentioned X-Fight being a pretty good ability, but Berserker isn't that bad either (assuming you ONLY have one Berserker and aren't trying to beat the game with four of them). There's a rare axe drop in one area of the first world, the Death Sickle, which makes the Berserker a great class in World 2. It's got very high attack for the section and a chance to proc instant death, which a surprising number of bosses are not immune to. The class gets an undeservedly bad reputation because of a select couple bosses in World 1 that the class is legitimately better off dead than alive in an FJF, but it's got its niche later on especially in the SNES/PSX versions of the game where you can underflow your magic stat to 255 with certain equipment
My current FJF run has been a real mixed bag with a pretty nasty World 1, Thief/Berserker might be the worst job combination in the game, but Ranger is good and Samurai can 1-2 shot entire bosses by itself so it's all uphill from here. About to fight World 2 Exdeath. In the endgame I'm probably going to use Equip Axes to put the Rune Axe on Thief, underflow my Berserker's magic to deal 9999 damage with the Gaia Hammer, and then put the Chicken Knife on my Ranger because its negative trait doesn't activate when you use it with X-Fight.
