I wonder how that trinket scales with holy damage for tank Paladins. If it does, then this would actually be a primary Paladin item, because no other class could use it in so many situations.
On the other hand I feel that many people do report anyone for ninja-looting just because someone rolled on an item they wanted to have. It happened to me yesterday as well on a Deadmines run, where I needed Cookie's weapon for a Paladin and immediately equipped it because it was a major upgrade compared to what I had on, yet 4 people instantly put me on ignore because "Healer rolling for dps gear?? OMG!" I wonder how these people imagine "healers" leveling up.
Maybe there should be some incentive for people to not report everyone as ninja-looter, because those people are equally disruptive to the community as the real ninja-looters. Hate grows where hate is sown. However I don't have any idea on how to do that in a fair manner.
