Okay if someone does tweening animation do not degrade their art for it. This is ridiculous. You should allow them to do whatever they want and not give them your stupid opinion. They do not need it. If they can only do tweening and they can only do certain things then let them do it. Do not go "oh you wont improve. Not a really an animator shut up. Shut up no one wanted your opinion shut up please. And if the post had nothing to do with you do not comment do not go oh wow dang tweening. ITS DISRESPECTFUL!! JUST RUDE!! THEY DO WHAT THEY WANT NO ONE WANTED UR OPINION
