Should there be set bonuses and proper gear sets? Yes. Will there ever be set bonuses and proper gear sets? No. Bungie has pretty much just made this Halo with a few RPG elements throw here and there. The only real tiers we have in gear are crap (anything below legendary), legendary, and slightly unique looking legenadaries (raid gear and exotics). Kinda hard to become legends when we can die from light level 5 enemies even when we are light level 335.
