Better idea (well..several):
Get rid of nodrop unique loot!
Get rid of the concept of the best items in the game obtainable via killing a single mob!
Get rid of mobs that take 50+ people to kill unless you feel like re-writing your graphical engine & net coding to make the game perform under conditions like that!
Make all of the very best items in the game obtainable from TRADESKILLS! T R A D E S K I L L S ! ! ! !
...and then mummify Tarasque, plant him in NLC, nuke Camelot to **** and turn it into a casino....a 0% casino no less...
