As much as I would live them to add trading I highly doubt they will.Also they epuld have to balance I'd say: -only trade gear of same rarity -You could only trade people stuff thats 15 max attack/defense higher than the lowest guardian thats in the trade(ex:I have a machine gun thats 319 attack and my friend is 300 light I cant trade him that machine gun for something cause its more than 15 attack above his light level.)maybe have some more restrictions but thats all I can think of.
