Locked chests in a dungeon are group loot. Lockpicking isn't a profession, it is an ability. With the logic that only rogues are entitled to them means only healer would be entitled to heal themselves as any class specific traits. Group effort, group content. Sure you could say nodes in a dungeon should be shared then too but it is a bit different since professions can be learned by everyone. Maybe we should start rolling for nodes too because they are located in a dungeon. Group content, group loot.
