@IzurichI mean I don't think that's really a fitting parallel, frankly. No amount of sheer bs anime superpowers is going to win this game is the point. The way I envisioned Medai it's straight up pointless trying to equal her in power - and all of that power has done absolutely zero good for her. If anything it's been a curse. I understand what you're saying don't get me wrong but even in the context of 40k a guardsman might think of a completely out of the box solution that goes infinitely better than just charging the enemy and hitting them with a sword.
Not to mention, at present Medai isn't at full blown living God strength - because that's kind of boring? She's powerful, very powerful, but with the sword in her chest I'd certainly no longer rank her in the top.
What's far more "powerful" in this context is, well, genre savviness as yam said.
But eh differences in perspective and I do really understand you. I just think that you're slightly missing a piece of the puzzle is all.
