Right now playing activities gives you the highest Tier you are able to get and Tier 1 gear. Let it be possible to get lower Tier gear by lowering the activity difficulty. Example: I am almost at max Light Level and I am getting Tier 5 loot almost everywhere. I decide to play a Pinnacle activity but I want to play at a lower difficulty to be able to finish faster. With how it works now I would only get Tier 1 gear unless I hit the B threshold, what I am suggesting is to give me Tier 3 or 4 gear for playing at a lower difficulty.
