A. to do the same thing as Reiner not going to save Eren: Reiner was a Titan back then plus he doesn't lose all of his head so even if Eren can do the same thing he can't grow up a new head. IMO, he is more restricted by something else.

Magath's tactic for Eren revolved around exhausting him by making him repedeately use Warhammer's power, and from the sheer amount of hardened constructs shown, it more or less worked out the intended way. Given Porco's example, I think we can take more or less for granted that the or 'stamia' refers to shifter's ability to repair and produce flesh.

So even if Eren by the power of bullshit can pull a Reiner, he'd need to create a Titan body to survive. And he shouldn't have the steam to do so as he is, pun not intended.
