Skill A for Veronica?

Though it's a rare skill, I have Atk/Spd Push on mine and it'd work well, though Atk +3 would be just as fine an A skill for her

I'd go with atk +3, mine is also +Spd and its worked well on her for me. Healers can't use fury btw, just like a lot of other skills unfortunately. Their options are pretty limited.

I mean, since you said you don't have rare skills (Close Counter, Bond skills, Atk/Spd Push 3), there's not really anything up to question. Your only options, assuming you want her as an offensive healer, are Attack +3 and Speed +3. So it's really just a matter of which aspect you want boosted: doubles or healing.

If you like taking risks give her Defiant Atk.

You can use brazen Atk/Spd if you still have Linus.
