Well, here are some more of my thoughts...
I still want trading to come to pass, but there still is that problem about people just getting a bunch of weapons and not even trying to get any themselves. That kinda bothers me because most of the fun of getting a Legendary or Cursed weapon is the fact that you worked hard to get it, so you deserve it! I'm thinking that if they include trading, you should only be able to trade really high lvl weapons to other pirates close to your lvl, instead of just giving a really low lvl a Famed weapon and having them sell it, or they just keep it until they can actually use it. Disney will probably make trading only available to unlimited anyway, so that would help eliminate that problem...
Also, if you trade weapons to pirates near your lvl, Disney should make it so that if you are giving somebody a really good weapon the person that you are giving it to HAS to give you something of equal value, like a ton of gold (more than the sell value, because weapons always cost more than the sell value) or 2 rare or famed weapons. That way you don't just become all powerful without losing things as well.
Now, because the new clothes are so expensive, I don't think that you should be able to just give them to a fellow pirate, but they have to give you the same amount that you paid for them, if not more. Also, you should be able to trade the new clothes to other pirates who have the new clothes as well, like give them some special clothes, and they give you other clothes in return.
