Blame Bungie. Oh, let's make a game we plan to make many changes to but use an engine that's hard to modify. Fantastic.

While a lot of those tweaks would take time I don't think the infusion elemental orbs would. They've already had similar items like the glass needles or etheric light in the game, and we used to be able to re-roll guns for different perks (which included elemental changes as it was). While the rest of the ideas listed here would obviously take a long time to implement, this seems the most logical, especially since it easily solved the "problem" that was their reasoning for getting rid of elemental primaries in the first place. It would also decrease the reliance some have on the zhalo supercell during arc burn events. The rest, I agree that would take a lot of programming and time.

Hello, I am the author of that very long post. When I wrote the post I didn't expect Bungie to make any of it real. I just wanted them to consider the ideas I sent henceforth
