Except she won by rules, she could have killed the guy easily.
Considering the whole point though, now she must admit Roland can overpower the church and stop trying to steal his harem.
Likewise so could he. Even if the aim was off generally, he would have been going for bodyshots, as a headshot would have killed her instantly and no amount of Nana would have saved her. So if we're going for what didn't happen because of the rules, he probably still would have won.
That said, you are definitely correct on the latter. If she can fight three on her own, hallelujah for her, but no amount of these presumably fairly limited supersoldiers can stand up to a fusillade. Ranked fire decimates.
Ash: I won.
Roland: Sure.
Ash: I also admit you have the power to fight the church.
On her way to reunite with Tilly (Maggie is left in Border Town to act as messenger for both parties), Ash murder the church delegation to delay the news and give Roland more time to create more guns (it'll be a few more months before the church expect the delegation to return, meaning only after they realize the delegation is late that they'll suspect something)
Tilly Is extraordinary witch, intelligence enhancer. Which means she's crazily genius
Meanwhile Ash extraordinary, strength enhancer. Which means she's t-900 terminator superstrong
Scroll extraordinary, Perfect photo memory capturer. Which means she's living scanner
