New stuff making the old one obsolte is in use since the birth of MMORPGs and MMOs from the times of Ultima Online. Destiny is actually quite mercifull with this subject. As mentioned a prime example is the Fatebringer. A weapon that many love (including myself) and many want to love that dont own it yet. Even despite the fact of it being still 300 dmg is more then enough and can keep on its own against anything with a critical spot. I cant imagine now doing a Nightfall with Arc damage burn without it anymore. Vision of confluence is still top tier in scout rifles including the autofire mode and stability and one of its kind as primary with solar burn. I can FULLY understand the uproar of ppl that invested countless hours grinding the VoG on normal and hard trying to get lvl 30. I got to lvl 30 almost at the same time when the 33 vendor gear was put into the game after like 15 or more VoG completions. Was I mad? No I wasnt. Bcoz I know the concept of MMO - MMORPG hybrids like Destiny.
