Honestly i find trading not fun because the reward of getting the item itself is way better. Its not really hard to get legendaries if you do the crucible or high lvl missions. Sure getting items for other class types is annoying but its upgrade material so i still am fine with it. You got to work for your gear, and that's how every game should be. That's why Diablo removed trading legendaries and set items. It's all about the time and effort you put in. I'm not saying its a bad idea I just like the idea of earning it instead of having people just get items without doing the work. But the idea of having general speak or topic speak in game to have more interactions in the tower would be awesome. There are tons of players that don't even know about clans and what not and would help them develop as players substantially.
