How about making barbs Dex usefull and the more you have the more you can dodge Knocks. For example this is what Dex should be in a MMO game.
Dexterity (Dex)
Dexterity measures hand-eye coordination, agility, reflexes, and balance. This ability is the most important one for
rogues, but it’s also high on the list for characters who typically wear
light or medium armor (
rangers and
barbarians) or no armor at all (
monks,
wizards, and
sorcerers), and for anyone who wants to be a skilled archer.
You apply your character’s Dexterity modifier to:
- Reflex saving throws, for avoiding fireballs and other attacks that you can escape by moving quickly. GRRRR why dont they apply this to barbs!!!!!!!!
As far as I know Dex is just for crits on barbs in RO.
