It shouldn't be a choice between having fun and enjoying the game.
Anything you do at epic levels should do something twords etr otherwise it just causes a divide.
sagas should have stacks, on hard a little stack on elite a bigger stack on true elite a bigger stack 50 100 150 something like that for the small saga
Challenges make a new ingredient to turn in mats for comms 3 types of whatever amount = 150 comms give us some kind of reason to run them instead of just leaving another system behind.
Lots of ways this could be done many have been stated multiple times.
Personally i wish comms dropped like challenge mats did based on what you did in the quest breakable, kills, traps, no deaths, and xp pots all factored in and placed comms in your inventory or bag at quest completion.
