Trading won't work. Not in a game like destiny, reading means we will have an in game economy and 1 that's far too complex for the kiddies and 2 imagine what it would do when everyone is running around with top end gear. I'm not saying they couldn't make it so some gear wasn't available like raid gear. But it's the light levels. Think about it. Your buddy has got some great gear for you, you just ranked 20 and all the sudden this armour will give you 25 light levels and with some upgrades 29. No need to do any vanguard or other things. Don't get me wrong I would love a reading system but they would have to do a lot of work for it to happen and kids aren't that savy to play games with in game economy like trading.
