Thing that is, this game is also about egos. There are people that only want to be OP to prove themselves/other players that they are the best and don't care about if it's going to be bad for the game.
I also had the x4 bez with set effect that could be +'able, best rings ever in the game (and better than upgraded rulers). Ended up in the hands of Maha, though
For the bossdrops, just drop something that is *slightly* better than what can be obtained or something that can benefit to guilds, like a big crone drop, or exp pouches... No retardedly overpowered rings.
