Our skills are permanent. Our skills are not tied to the guns. In those games when level is increased the gear becomes obsolete and you level more skills to build your character so you get strong enough to conquer the new difficult content. Sounds the same to me. Next dlc Destiny gets new skills. It is a seasonal artifact, that takes like 2 weeks to max out. I don't think any other game let's you move gear with you, except Division 1. The seasonal reset and light increase gives people something to do, the gear retirement gives people a reason to chase and use new gear. I like playing the game but I also like having objectives, these resets add more reasons to play longer.
