While Ragna may have better normals than Tsubaki and specials that get the job done in a similar fashion, he does not have access to the speed Tsubaki has nor does he have charge canceling. Tsubaki is faster and has a much better mixup. Tsubaki may require more hits than most of the cast, but she has the tools to get those hits as well.

Your own 5A/2A have 6 frame startups. Very useful for getting out of blockstrings in the right places. A successful 5A/2A will give you your 5BB combo. Damage will be prorated down to 1600's, but that's a freebie for getting the opponent off of you. Because of this I would refrain from doing anything else off of 5A/2A under pressure. Don't need to be wasting charges for significantly less damage.
