The Spell cancel infinite combo makes it much easier on Raine, though Genis was still hell even with that.
For those that don't know, when you do a combo with Raine (2 hits), there's a delay between the second hit and the start of another combo. If you start casting a spell and immediately cancel it and start a combo again, you can get a shorter delay between combos than the delay between hit #1 and hit #2, making a near infinite combo.
