They also get Shield Battery which increases your HP, SP, FP regen slightly, which is not incrediably useful imformation. The reason to go Destroyer is to get the next up class at level(RF Online Gold) 40. Now, Gladius is great. Gladius has both a defensive skill that requires a shield, like Bellato's miller, and a great buff that increases attack speed. At level 40 you can pick from Punisher, Assaulter, Mercenary.
Punisher is the reason to get destroyer because it has a snare. Unlike Bellato and Cora, Accretia don't have the "spin-a-web" skill that slows people. So they need a punisher with Magnetic net which holds someone in place for 20 seconds. Punisher also gets a high damage attack called Rage Blow which on attack debuffs the image, making them slowly lose health(RF Online Gold). This debuff can be removed like any other.
Assaulter is a great middle class. It has an attack buff called Capacity engine and being the class in the middle it means either can take it. So you can use that to make your extra mangle attack better, or we personally find it better to go Gladius>Assaulter to have both a damage and attack speed buff. It also has Limit guage, which inreases the defensive guage.You can Buy RF Online.
Mercenary is the next up on defense. It gets Excel Charger that increases the effect of healing potions. Keep in mind you could have 15,000+ hp and the best potions you can have are 5k heal every 3 seconds so this is definantly a useful skill. However, it will take another buff spot. Then there is Powerful Element which increases elemental resistances, more defense, and higher block rate and requires a shield to be used(rf gold).
