I feel like it's a good skill, but I'm not sure who to give it to. Who do you guys think can utilize this skill the most? From the top of my head, I can only think of BK.
You can either give it to heroes who have good defense and lower speed, so that they can avoid some follow-up attacks in the enemy phase (BK is actually a good pick there), or you can give it to heroes with good def and speed, so that they can perform follow-up attacks (Nephenee comes to mind, but she already has that skill as her weapon refine).
It definitely looks like a good substitute, if you don't have a bond skill to give her. Her weapon's bond already makes her more of an enemy phase hero, so a stance skill just expands on that. I'm kind of unsure about her attack tho, as it's rather low, but the TT bonus in arena should do the job and if you'll also give her bonfire as her special, she'll actually deal a lot of damage with it if she has her skills active (38 def, which means 19 bonfire dmg). The B skill seems alright for arena purposes, especially against armored unit who are constantly boosting their specials. You could also consider wrath, but it's quite expensive and probably not worth the cost.
The C skill can be something simple like atk smoke or a buff of some sorts, depending on her team. Drive speed is one of the safest bets, but considering that she will usually be close to her allies, you can give her a dual spur (like spur def/res from Morgan or atk/res from Libra). The seal depends on which ones you have free, but close def seems perfect and atk/def2 would give her some important stats.
Overall, a pretty good idea, although she would be very enemy phase reliant. I'd also say not to commit to it just yet, if you are not completely sure..the dual rally and the stance skill are pretty rare afterall.
