...should I ignore finishers during Shadow Dance and just spam Ambush?
Of course this is only if I don't have to refresh Rup/SnD/Recup, but you try to time your dances anyway, so...
Basically, I noticed that Evis rarely deals as much damage as Ambush, while the latter always hits like a truck, being a guaranteed crit and everything. I'm pretty much only hitting Evis during SD time because CPs are capped.
