At this time Yin is currently unplayable in CO. It lacks certain powersets in order for me to play him properly, therefore, I'm having to fudge the character and it just isn't working out. I talked to Morc and liquidz yesterday about it and decided what might be best if Yin had to take a leave of absence and sent in someone to take his place while he was on leave. The character I created was experimental, but I enjoy him. He's a fire/ice elemental and I had a little bit of fun playing him.
So this is what may happen as we come closer to launch.
