Easy fix for all the comments. Player to Player trading costs no strange coins or motes, but the player must trade an item of equal rarity to the other player(Exotic-Exotic, Legendary-Legendary) so that players don't get scammed or feel they got the crap end of the deal. I also like the trading vendor, where you can choose an item of equal rarity to swap out for(Vendor has all items except raid and bounty items), but at an additional cost(10 strange coins for a weapons swap & 10 motes of light of a armor swap).
