Before some of you start with the raging and sarcastic comments, I'd like to say that trade-able elixirs have worked well in Arcane Legends.
There's nothing to explain here. All I have to say is that people would buy elixirs to get a good amount of gold for them. This results in more platinum purchases, so it is good for STS. And obviously it would benefit the players as well.
If you happen to disagree with me, please don't make sarcastic comments. I appreciate a logically backed opinion.
