Not really. The game is based on RNG, so if trading was integrated then players would be able to get rare weapons or armor from their friends who have gotton more than one. Example: i've spent the last few months trying to get a party crasher....i finally got one last week. What's hilarious is that i have friends that have gotten like 4 or 5 of them already, some on the post match reward screen right before my eyes. I could have gotten one from a friend instead.
