100% agree. Your idea just adds more incentive to grind, which is in Bungie's favor. I wouldn't mind grinding for matching armor sets, if it offered a nice little benefit. The perk options are nearly endless and don't have to be outrageous, or game-breaking. I like the faster reload/increased ammo capacity idea, or slight boost to weapon stats (like, 1 or 2% - again, not game breaking, but the difference between dead and 1 or 2 hit points, so escapability is slightly increased). Or, slightly increase blink distance.
