In my opinion the anime did a good job at showcasing Armin's character development. While he indeed was a 'crybaby', as you put it, he realized he doesn't need to be a burden and moved forward. I think his actions show it, not only he is the strategical mind behind many plans, he even confronted Annie, and not just once, but twice.
