Sunsetting weapons will make them obsolete in MOST of the game. Not just Raids, Trials, IB. All seasonal content is light DEPENDENT. So when new seasons drop, and new activities, and the activities that linger, you will HAVE to use gear that gives you the highest EFFECTIVE light possible. So no, you won't be using your sunset gear in "most" of the game. They should sunset vendor, and world drop gear to make room for new vendor and world drop gear. They should not sunset ANYTHING that required a quest or time investment to acquire. As described it is an exercise in stupidity. **Edit** The one thing people should consider: It doesn't need to be this way. World drops, are the gear that should be rotated in and out. Banshee, Zavala, Shax... That is where you pad the loot pool, update it annually, sunset the old gear, keep the game fresh. Seasonal gear, quest gear, pinnacles... This gear should not have a power cap. This gear is not just random. People actually invest time in it. So the seasonal/quest gear needs to be unique. Give people a reason to use one thing over another. As presented, all they are doing is the same thing they always do. Controlling player choice to cover up a lack of creativity.
