Well, the vigor buff we all know and love. Opposite mechanics of pride except exponential (kinda) decrease in effect, calculated in it's own multiplier kind of deal. Isis is one of the most notable ones when it comes to dummy-kun.
Ah... the beauty of Shingen BG MEX. Instant +20BG to all, and then skill 1. Voila.50BG
Dummy-kun does punch you, sometimes with wet noodle damage and sometimes hard, although strats do exist to keep vigor up in spite of damage... even for off-element use.Does dummy punch you?
I'd like to point out that having 2 PF FB is pointless in that particular dummy-kun because the only score that matters is your highest, not your total.2 FB
Still, how does that fare in normal combat? You have a pattern of 10T for the first potential FB, followed by 5T before you pull off the next one, then 10T again. 7.5T per 2 PF FB. Well you've just dedicated one slot in your team for an FB slave. Which tbh, light doesn't really need, since there are setups for them to consistently burst every 4T or less, while still having other skills that are buff or utility in nature.
And Mike AW already exists to add +20BG to everyone after she bursts. Have her and Nike in the same team, the value of Nike's instant everyone burst kind of drops a bit, you might as well just use something else.
Being a buff slave wise, 12T isn't too bad for keeping up 120% assault, but then she does literally nothing other than buff. And this kinda setup is better in a war of attrition, so you'd probably run Sol. And now you have 2 slowpokes to hold back your burst. Run a Tish to try and keep them up sure, but it's gonna be a real hassle. The damage output tanks pretty significantly if you can't burst quickly.
What Nike needs 35 turns to accomplish, other setups can probably accomplish 5 times over. This is why I don't exactly like the idea the Nike is the queen of slowpokes, what she does isn't amazing in retrospect of taking 35 turns to set up. And already, being either slave isn't exactly the best option because light has so many multi-utility himes coming right up.Fight is atrociosuly long
And even if you do, the only place where that's super practical, hrags, due to the massive HP, and assuming you survive that long... no one's gonna wait for you to take a whole lotta turns to do massive damage. While you're setting up a faster team would've sniped MVP already. You might as well make yourself more useful running a support build. Which isn't to mention that you probably won't survive that long.
