Sorry but this Thread is so stupid... when the game editor comes out there will be Plenty of Mods with "uber weapons" if u let the drop always be the same they would be even more encouraged to use those Mods.. so simply let it be as it is
That being said (sorry for the harsh words) here a Solution that would benefit everyone (But i dont think its even worth wasting developing time for that): -Give the Bosses Much better Loot -Reduce the Loot of the "Boss Chests" -Disable Saving during Combat
