Yes. warriors only good in damages from lv90 onwards.
For Crusader, its only when they max panic(lv30) and combo(lv30)
then they can deal a lot more. otherwise lv8x sins with shadow
partner maxed sure win one.
For Dragonknight, they have mostly range attack. If count solo
attack damages, sure lose to sins. Also slow in attack.
For whiteknight, got elemental plus the ability to freeze using ice
charge. Also need to be lv90 to max ice charge(lv30) and charge
blow(lv30).
Its only lv90 onwards then damages start to even out for warriors
vs sins and sadly, i can never reach lv90
