Well it would be useful if they could limit trading to level 28's and up, or something like that. That way, people have already likely gotten good at the game. I would hate to play a strike with a couple of level 29s who have the skillset of level 22s just because they traded their way up. I suppose that's my other main concern. But I see no problem with what you're talking about, just like I wouldn't mind getting warlock raid gloves from a buddy who has multiples, maybe in exchange for one of my multiple Patience and Time rifles or something like that (well..... before Xur sold it, that is... lol) But yeah, trading would help me out in some situations, sure; however, I still think it's such a rewarding experience to finally get that drop when you've been waiting so long. And to limit the no-skill people that want to trade their way to the top? A minimum level restriction could be implemented like I suggested. That's the only way I'd feel decent about trading being allowed.
