My two cents about his growth, Obito did not survive hand to hand with Minato because of his skill..he survived due to his advanced Kamui. Using a basic SG he still is able to move, phase and enter his dimension. He knew the work arounds to Minato's FTG 1 jutsu. The fight wasn't some epic long battle it barely lasted. It was FTG vs Kamui, T/S vs T/S. Obito lost that battle (battle of jutsu speed) Obito even lost to Kakashi when he warped Naruto. Obito went to credit Kakashi by saying he was faster than the knife and chains he was spewing out. Only way I can see Obito's growth, maybe he fused with the Zetsu to appear older or an adult. Or maybe just that Zetsu became apart of him completely..and in the process he wears a mask out of respect (long shot lol) I mean there are ways around the whole "growth" issue bro.
