I guarantee he will use dragon force again he just hasnt been put into a situation where the conditions created it. The first time he used it was because he ate etherion the second time (which was different) Jellal gave him the golden flame which resulted in a less powerful dragon force than the first one. Keeping God slayer magic would have been ridiculous, he ate the black flames AFTER he released all his magic so he literally ate it because of his bodys conditioning and immunization to fire and heat vs absorbing it magically like laxus' flame. He still can activate lighting dragon mode but after one attack he would be burned out (like he mentioned to max) so using it during a fight would be dumb because if he missed then he would be vulnerable. The fflames of emotion was written when mash thought the FT fighting festival was the last arc and they didnt make that much of a difference anyways... Either way logically he is a solid character people choose to hate on him because they want to see other characters ib the spotlight more which again, is cool but however in English class you learn that the narrator ie Lucy is not the MAIN character, Natsu is.
