Honestly, the best decision would be to let chaox stay and have Regi manage the team so at least they are not butting heads in game and Regi can make unbiased decisions about what is best for the team

I'd hate to point fingures, but being a manager and a player is simply a conflict of interests, the decision that Regi made to let Chaox go completely biased because he was a player, if Regi was simply a manager he could make unbiased decisions about what is best for the team, until Regi understands this simple concept, he will continue to drag this team down and keep TSM from becoming the best team they can be.
