See, I love spreadsheets and being able to optimise things, but I do need to actually be able to feel the impact in the gameplay, too. And yeah, Destiny is terrible for that; the buffs and upgrades you do get just feel irrelevant, for the most part. Especially with the terrible scaling system they use where you never feel any stronger against weaker enemies, just weaker against stronger enemies. When getting a huge numerical upgrade (in terms of gear score) doesn't change anything about how the game feels to play, I think that's poor design.
