Which am I better off with?

I'm almost 100% sure that it was the 8% magic that gave you the boost that you lost (the 8k higher you hit before), but more crit rate is always good, although now is like 150% your normal damage instead of the 200% it used to be but I'm pretty sure the SE from gloves makes that higher and also I would bet other buff would have a bigger impact in your damage with a higher crit rate.
