What Mirajane icon dude said^^ Also, remember when Jellal was going to be taken to jail and everyone fought to stop it except for Erza? She was, obviously, the one who didn't want Jellal to be taken away the most but was also the only one who didn't fight, and the one who eventually stopped it. So yeah, Erza is the exact opposite of what you said. The only times Erza has been really shown to be "immature" is during comic relief moments.
