Me and a friend were playing the game, and a blue chestpiece perfect for my juggernaut dropped. Needless to say, I needed it, but my friend pressed need without realizing it. They apologized, but it was no use. Since they needed and got the item, it was completely impossible to ever get that chest piece without hours of grinding or doing the heroic, which was nearly impossible for us.
TL;DR: Trade and Mail limitations should have exceptions for gear that was won in a roll.
I am a freeper and can receive credits and items just fine but I cannot send any. This means that all subscribers have been blocked from receiving mail from a whole lot of f2p people but we can all receive mail from everyone. It is odd that more people have not noticed this.
