Crit Defense?
I was playing an MMO that included a stat with its armors that in addition to the typical damage mitigation provided by building defenses, reduced the incoming critical hit chance. The stat was called "Protection" and reduced the likelihood that the opponent could land a critical hit by some % up to 30%.
I was thinking about it, and I think there are cases where this small addition, say a 5% or 10% on an item or two that could protect tanks from opponents who stack critical rates as well as damage. I'm aware that this may be a silly idea, but i'm interested in what the community thinks of it.
