3 questions: 1) Are you talking about an individual item not being higher than the one currently equipped? 2) What is your current light level with max gear on? 3) What was the light level of the item that dropped? Going off your currently equipped gear on your Warlock (I just went with the highest light character you had), I would say your warlock is @ 1325 2/8. This would mean your pinnacle drops from playlist activities would be dropping @ 1326. If it fell into your 1326 equipped gear, then no, it isn't going to be an improvement. You need an energy weapon, power weapon, or boots to drop, nothing else will help you increase. The grind is SUPER slow if you are simply doing playlist activites alone, and the RNG behind it will feel painful when you don't get the drops you need. If you have access to other pinnacle activities other than playlist ones, I suggest doing them too weekly.

Post a video showing the reward you received upon getting the weekly completion.
