I like this idea op, how i would love to get to go karazhan again . But as someone else here pointed out, lore and boss drops don't seem to be considered in lore. some loot drops make sense like bosses wielding the weapon and later dropping it, looting something like ragnaros's hammer does not make much sense though, given how huge it is. Like 5 taurens or more put together. You would need an abomination tauren at best, to make sense of that.
