Are crits without finesse stronger than crits with finesse?
Without finesse stronger...
Because the only thing that doing Finesse is increasing your critical chance on 10%, but increasing DR of a target on 30%.
With Finesse you'll crit more often, but damage always will be lower.
Finesse is must-have for cripplers, who don't care about damage, because hands have low critical multiplier, so Finesse gives alot advantage.
If you want to do damage, then don't pick Finesse.
