Why do you fail to realize that he is a member of the DoA family who SOME of us want back. He won't be OP like he was in DoA2U, TN knows for sure not to do that. Why the hell would you want to STOP him from coming back to the game, he'll be someone who's just easy for you to beat while those of us who WANT him back will have our desires fulfilled, regardless to whether he sucks or not.
You are not the only person in this community who matters, we are ALL a community and if some of us want him back and TN has decided to fulfill our dreams, what is WRONG with them doing that? Stop being self-orientated and start looking at the world around you, Tengu coming back should not be stopped because if some of us want him back, then there's nothing wrong with TN bringing him back.
