Its a good idea but with some changes. For example:
*stage one--- pay black prince 250.000 gold to lend you some dragon power
*stage two--- Use dragon power on xxx orc boss and capture its essence
*stage 3---Bring essence to black prince
*stage 4---Collect 400 x living steel like material
*stage 5---Give this material too the blacksmith too craft you a weapon mold (there was a blacksmith in outland near the blood elf area)
*stage 6---Blacksmith ask you for a essence and that you need too infuse weapon mold on a toxic mountain (a place with lvl 300 elites)
*stage 7---After you obtain the toxic item you need to give it too blacksmith....but he wants you to pay him 500.000 gold for his work
*stage 8---Bring the epic weapon to last boss and once he dies stab him with it and let the weapon be infused with titan energys (this boss is only posible to reach in 20 man heroic)
*stage 9---Bring the infused epic weapon to black prince and he will infuse it for you (for a price)
And here is your legendary weapon:
