I would like to see the light level cap of decrypted engrams raised to the character's light level. The endgame grind is just too limited in repetitive and this would open up all other parts of the game to high light players and make it rewarding. To hit 320 you would still have to run the endgame content but this makes leveling the new IB, trials, or exotic gear less tedious and would allow players to play around with the different weapon types rather than holding to one set and the subclass it happens to be geared to.
