Yes this is yet another post talking about seasonal resets but as the devs said they are willing to discuss it, here I am to give my take on them.
The goal of a seasonal reset is to allow players that thrill of chasing for the better gear once again, if new content gets added and players can go through all of it in seconds yeah it might feel like updates bring nothing and this might create low quality content just to bring higher quantity.
The issue is: most people don't like to lose what they worked for. In my opinion the best compromise that has been achieved in other games (and generally appreciated by players) is to simply have a prestige system. You get rewarded for resetting but you always have the option to keep your progress. Something like a dungeon tier that only unlocks once you prestige a couple of time would work for example or simply cosmetics given for resetting. I don't think the idea of a reset is a bad concept I just think forcing it on people is. While my ideas of what could be used to incentivize people to reset are perhaps not the greatest I do believe they are simply there to show that with incentive most people wouldn't mind the system.
