Long and short of it. I changed a Ring which allowed me to maintain hit cap while boosting my ST. It also allowed me to drop a Hit gem.
I gained:
38 Strength
42 Haste Rating
I lost:
33 Expertise Rating (dropping me to 5% from 6%)
49 Crit Rating
While I wasn't Exp capped before, I was pretty close. Is the upgrade to ST worth an extra 1% chance of having my stuff Dodged?
