Forum:Should there be unit trading?

In my opinion, there should definitely be unit trading or marketing. Although it could ruin the "find and capture" effect of the game, I'm kind of sick of waiting until Tuesday for phantom pots, and I need just two to evolve my Alyut into his Holy Warrior form. I went through it 6-7 times (Mind you I'm rank 35, so I had to wait periodically throughout the day) and I acquired only one. Why you may ask? Because 90% of it was Lightning, Earth, or Fire. I obtained a total of 8 lightning pots, and 5 earth pots. I wish I could trade them off to someone else, as all it's doing is taking up unit space. Then I could actually achieve something. What are you guys thinking?
