My bad, I was actually trying to say their usage is limited. It was a bad choice of words on my part, I guess. And it's not that I don't agree with what you're saying. It's just that the spoiler gives the impression that they awakened their abilities during the fight, which is not necessarily the case. I think if they have these powers before rooftop, they should be able to use them better. Zoro, for example, masted Enma in a few days. Luffy awakened and masted advCOA during Udon, and he literally learned to infuse his attacks with COC like a few minutes ago and already started fighting so well against Kaido. Therefore, it doesn't necessarily take so long to master new found abilities.
That's why many automatically assumed their powers awakened during the fight; that is also the reason why we're seeing a lot of people, especially Luffy fans, complaining about their powers being asspulls. It also kinda goes in line with them not trying these abilities atop the roof. I know people don't always use all of their abilities, but it worth noting that this does indeed go in line with their rooftop battle.
