If the game is based off of teamwork and you want us to work together in the most productive way possible, why can't we better each other through trade? There have been events where I got a iteam that wasnt for my class but was for my teammates class and I wished I could have give it to him so he can progress. The advantages of adding a trade system can be endless but most important, its part of teamwork. When was the last time you wish you could have been helped out by a friend?
