So what you're saying is that taking over a weak Demon and taking over a powerful Demon like Sayla should require the same amount of effort? Get out of here with that nonsense! At the beginning of the match when Mirajane was trying to Take Over Sayla's abilities, she was in the middle of a very tough battle and I don't know about you, but I imagine that trying to Take Over someone as powerful as Sayla while fighting her would be extremely difficult. At the end, when she finally does succeed in taking over Macro, Mirajane is no longer fighting or trying to multi-task. She's clinging on to Sayla for dear life and putting everything she's got into Taking Over her power. And that's why she succeeded. Yet, all you noticed was the speech she gave while doing it. You paid absolutely no attention to the context of the battle at that point.

When Mirajane, and anyone else for that matter, normally takes over someone, they don't just get one ability, they pretty much become the thing they Take Over. Mirajane managed to only Take Over Sayla's curse, when we saw clearly that Sayla was packing a hell of a lot more punch, so no, I don't find it BS.
