Yes they should idk if this is true but I heard a rumor that they intended to but later messed up the coding and couldn't fix it in time. But they say with trading people look more skilled. That is BS because they made the game based around an random number generator system. So my point is that if (just for example) we both have last words that doesn't mean we're at all good with them and even did anything to deserve them. So overall yes they should add trading.
