The only possible "crit" based class is bards.

Please, my god, please understand that "big crits" are meaningless.

In fact, because of life surge, you actually want crit LESS than before, because of your autocrit ability.

The more autocrits you have, the less crit you need, aka, monks, especially.

Not a single damn class is a crit class over any other class aside from bard.

And its been found that bard doesn't...really even favor crit much more than any other class.

People need to stop thinking "oo big numbers" and think that crit is the only thing that contributes to those numbers.

Instead, think this: Would you rather have fewer crits, but bigger crits, or more crits but smaller crits?

Suddenly thats not so easy to answer. And thus, why we have stat weights.
