Let us build our own weapons...example,  have your rare weapons (or any) be able to be increased to legendary,  this could be with the use of a item such as how etheric light was used, then we can obtain, through the nightfall or daily (that makes those playable again), weapon perk modifiers that then can be turned into the gunsmith so he can forge the pieces together.   Build your own weapons but you can only gain the materials through nightfall so not everyone gets everything so fast, so when you do get all your favorite perks to build your gun...it's exciting lol Oh and bring back the blue flame ! I know this was used to show your boost in experience you use to gain by completing the nightfall,  but , since you made that irrelevant like so much of the game, those rep boosters we find, just have the nightfall give you a random one for the week( so if you had, for example,  the crucible one, you will be more inclined to play crucible that week).  One more note....3 of coins needs to go, the exotic drop rate in year 1 for nightfall was good, and exotics were hard to come by, so along with the experience boost it made the nightfall a must do activity.  Now it's a pointless effort because exotics are so easy to get.   I mean they are "exotic " and shouldn't be so easy to obtain.   Just sayin
