I'm glad to see a lot of you don't really have a need for trading, because people won't work for their weapons, because there are people who get like famed or World Eater every day and have no problem with getting it again. Then everyone gets great weapons every day and would get bored and quit. I'd actually like it if it's like famed for famed or legendary for legendary, but think of the hackers out there, we might end up with a glitch where we can lose our weapons to them and get a horrible one in return, or none at all.
Remember, don't blame Potco for lack of content, blame disney. If you watch disney, see how much Club Penguin commercials you see ( I've gone up to 50 in little time. ) then you see no Potco commercials, disney puts more time and money into Club Penguin instead of Potco, which leaves us less to work with.
