and to the poster above me, im guessing its because versatility seems to be harder to get your hands on in big numbers compared to mastery, seeing as the cloak is 100 and neck 75 an rings 50 of the stats
I get what you're saying, but that still wouldn't really make sense to me. Aren't the mastery enchants giving the same amount of mastery as the versatility enchants give versatility? Then if mastery is the highest prioritized stat, shouldn't those enchants be chosen? Unless I'm getting something wrong.
