Trading has always been a hot seat issue as many would think this is game breaking. I used to be a proponent of no trading but I have recently changed my mind since TTK was released. I think there are easy rules to make a trading system work. Commons for commons Uncommon for uncommon Rare for rare Legendaries for legendaries, [b][u]but[/u][/b]: Gun rules: Light level must be equal or within a range of 5. You cannot trade a 310 for a 250 legendary. If it is a raid legendary or ToO legendary is must be traded for a ToO or raid legendary respectively (305 defiance of Yasmin for a 310 doom of chelchis). All other legendaries must just be at equal light level and fully upgraded. This way people are putting time and energy into each legendary and not simply gaining hard to earn guns for no reason. Adept and Harrowed guns can only be traded for adept and harrowed weapons as well. Armor rules: Raid gear: same rules as the weapons, range of light levels by 5, raid gear for raid gear, it can be for cross class (Titan helmet for warlock chest piece). Trials gear: same rules as raid with light range of 5, ToO for ToO, but no cross class. Armor drops are guaranteed and can be ran on all characters. You can trade armor to get better perks. Exotic weapons: Exotic weapons can be traded for light level range of 5, must be 300 or above, must be fully upgraded, and can only be traded for other RNG exotics (hawkmoon, thorn, mida). Quest rewards cannot be traded. Class exclusive weapons cannot be traded. Raid exotics cannot be traded. Exotic armor: Same rules as trials gear/exotic weapons, no cross class trading, above 300 light, fully upgraded, and can be traded for other pieces of class exotic armor (chest for helmet). Materials: you can trade materials (armor materials, weapon parts, and upgrade materials) for one another in a player based exchange. Sparrows: players that have engaged in silver purchases and not got the sparrow they desired can trade it to another person for a sparrow from SRL or eververse trading company Shaders: these can be traded as long as they are RNG based and not quest based (Queens web vs. Artic proxy) Ghosts: ghosts cannot be traded Artifacts: artifacts cannot be traded Cloaks, bonds, and marks cannot be traded Emotes cannot be traded I believe this will help create a trading mechanism and a flourishing economy without breaking the game.
