I got to try the ring out on the PTS in Vaneshran, and it actually felt really good, even with my mediocre dps. This item could have real potential for solo play and could give some of the struggling overland solo players a bit of help. It's a cool item, and there was really no need to dial it back the way you did. To keep it from being overpowered in trials, just add in a scaling effect so that for each person in your group, the efficacy is reduced by 5%. That means it'll still be somewhat strong in 4 person, but pretty useless in 12 person, where it could potentially eliminate the need for any healers and add even more power creep.
