Right now there’s no point in going out doing patrols and public events collecting chest or planetary materials. Adding a grandmaster mode that has higher tier drops like enhancement cores, exotics, or higher stat armor and weapons would bring a meaning back to patrols, you just stay in for as long as you like and other guardians patrolling by can hop in to and help. It shouldn’t give out loot on the scale that grandmasters does with all the ascendant shards and adept weapons, but it should be a good place to grind for exp, gear and enhancement materials. Possible higher level bounties as well.
