Ahh. A fellow Warframe player. I like you already.
About thr topic… there arent enough various items in this game to make it tradeable. If they added improving the quality of an item, like, a forge where you can add up to 10% more power max or a way of giving the items varied properties like Warframe has woth riven mods, that would be different. I think they should add that. If there was more variation, it would make sense. And if it were possible to farm for specific items (like, have different ways of getting different items) or craft items, it would make sense. But in its current state, trading would only harm Super Mechs
