Ring combinations and other qns.

dragon knights get a lot from it too, 30% crit chance and also an increase in base for all our attacks. but yea, pallies and DrK get a good chunk from it, also, aren't pallies like 54% crit with CO?

EDIT: holy crap, potentialable, +17 attack and like 25 all stat rings? god

Base crit rate doesn't actually improve the damage increase of the crit ring, thanks to marginal differences.

On a class with 5% crit (20-50%): +10% crit rate -> 1.75% damage increase from crit becomes 5.25% damage increase from crit (relative, 3.44% increase in damage due to the ring)
On a class with 55% crit (20-50%): +10% crit rate -> 19.25% damage increase from crit becomes 22.75% damage increase from crit (relative, 2.94% increase in damage due to the ring)

It's classes with extra crit damage that benefit most from the crit rings: Bowmen and DBs obviously (SE/Thorns), but also Paladins, Dark Knights and Gunslingers, since they have min crit damage boosts.

And it's bad for Heroes cause they have a damage nerf to crits, it only does 10~25% extra damage.
