Had to group up (rare hunting parties) to get mine and beg the others in the group to trade me the items (some weren’t even cloth wearers), very disgraceful but I really wanted the “rare” tint for this priest.
Did it before the rares nerf, though, so it’s probably even worse now. Note that the items are dropped by specific rares, so if you only lack certain slots, there’s not much use to kill other rares than than the one who has your items on the loot table. Also, farming (camping) the trash piles can help, they have a chance to give you green soulbound drops with the same skin as the rare mobs drop.
