title says it. i think its better to have this feature so that we can enjoy playing with cool weapons even in low levels. and not only open legendary chest only when you reach level 100.
having able to upgrade weapon power level would be nice idea IMO. it will saves us using GOLD. it gets boring when you farm gold in same dungeon (dark barrow boss) over and over, in addition the should put gold rewards in the end of dungeon instead of having exp rewards (btw sorry for my English) :)
