How will NIN nerfs affect them?

[Alistaire]

The difference is very small though...

It's not about how much of a gain it is; it's about how likely it was that SE overlooked it. And we don't know how much of a nerf this will be, could be 10 potency. You're absolutely right about what you say but it's also much more likely that SE already took that into account.

Well, they overlooked STR accessories in spite of having that exact same issue like 3-4 patches before. They overlooked Holy upon ARR release when it had 260 potency with no fall-off. I'm more inclined to believe they overlooked the obvious nowadays.

As for how much of a nerf: Even a 5 potency nerf would more than make up for the TCJ increase. You will use one Gust Slash every 6 seconds, which means after 72 seconds, you already made up for that unintended damage increase via TCJ.
