Uh.... Gajeel had proper development after that plus we saw Makarov's speech to him and Juvia revealed how he really is under his harsh exterior so you are just bringing up old news. Minerva doesn't have those same conditions but her biggest fault is for converting way too quickly. Gajeel's one wasn't on the spot, it was gradual, first arising from genuine battle discipline after losing to Natsu.
