Godlike
Yuna (FFX) vs. Lady (SH3): Some people are SORELY underrating Anima's durability and damage. Not seeing Lady have much of a chance here as a result.
False Althena (L:EBC) vs. Rika (PS4): Big massive OHKO Magic damage moves are Rika's bane, at least when they aren't Fire.
Heavy
Sir Leopold (DQ8) vs. Largo (TotA): I can kind of vote on this, having seen Largo 1! But yeah, I won't.
Arc Eda Ricolne (AtLC) vs. Sync (TotA): And by definition, same applies here (ok, not really, since this would require me to have played both DQ8 and AtLC...which granted I have...but wouldn't be the case for others <_<)
Middle
Lani (FF9) vs. Yuki (G3): Not seeing Flash > Magic.
Alice Elliot (SH1) vs. Paine (FFX-2): I think? Not sure, but kneejerking.
Light
Shana (LoD) vs. Fu So Ya (FF4): Think I see stop hitting turn 1 since its sickeningly accurate in game, even against things with maxed out Magic Defensive stats.
Zhuzhen Liu (SH1) vs. Dinn (S5): I'm going to resort to Zhuzhen's Healing > Dinn or something.
Regarding Dragoon transformation...
Its a Free Action, the same way as Shadow Hearts Fusions are. She can use her transformation with no turn loss, HOWEVER, naturally, she still actually needs a turn to transform. So yeah, regardless, Shana's got one turn where she's vulnerable. And LoD has status that stop you from acting, which you can't use Dragoon to transform out of since you can't act, so...yeah, Stop is pretty clear cut good enough assuming it hits (at least, I think that's the argument here?)
Also, regarding Defend Strategy?
Let me demonstrate why that fails:
Shana opens with Defend!
Fu So Ya casts Blink on Self!
Shana attacks, misses, fails to gain SP since IIRC, you need to actually HIT to gain SP (if I am remembering LoD properly, if you miss the Addition, the attack falters on the first hit, not even allowing you to get an addition in...granted, Shana lacks additions.)
Shana...might double turn here, but then Fu So Ya just casts Blink, and we're back to square 1 until Shana fails to double turn. At that point, Fu So Ya gets damage in.
Granted, there's a chance Shana double turns often enough (Fu is slow, after all) that she could run Fu So Ya out of MP, but would need to look stuff up.
Point is, if Shana tries to Defend until double turn or something, Fu casts Blink and thinks get messy.
