Fun Fact: Aside from the obvious effect, Equip Bows also grants the recipient character the Strength and Agility of Hunters, both of which are quite a bit higher than a Berserker's. Give it to a Berserker, then equip said Berserker with the Hayate/Gale Bow. You now have a character that is very fast, very strong, has innate Confuse immunity due to being constantly Berserked, gets a 50% damage boost from said Berserk status and uses X-fight about 25% of the time. Since s/he's wielding a Bow, s/he also does the same damage from the Back Row, allowing you to equip gear that's weaker in terms of defense but grants boosts to Strength and Agility, then just put said character in the BR. All of this together made said Berserker my biggest damage dealer by a long shot.
Hell, even just the Equip Bows command greatly increases the Berserker's power by virtue of making him/her far faster AND raising his/her strength, even when you never actually equip a bow to begin with. It's things like these why I love FFV ^_^. With the right strategy and ability combinations, you can turn even 'weak' classes into powerhouses.
