It is as a fellow post suggested…. “A form of continuing Sunsetting” They did it with warmind mods by making them extremely expensive and nerfing them, now most players do not use them. They are continuing on the trend by making the orbs of light mods harder to activate, basically nerfing them, making them obsolete for the most part. Bungie either have a very immature designer working on mods now …insert tantrum voice “I want them using my mods now not those old ones they actually like” stamps foot…. Or… It’s just Bungie’s continued desire to create grind, therefore content out of thin air.
