"well spaced" pressure being what..? most of ragna's damage, mix up and pressure (+pressure resets) require close range.. which 623c also hits at. 6b 6d 2d are advantage on block, continue pressure & bait dp from there.. 5b 2b 5c are jump cancel-able, always safe on block, along with jabs of course.. only true unsafe normal is 6a, and mostly unsafe are 3c and 6c which can be special canceled to 236a. 5d as well, but can be considered safe with 25 meter. 236a is -6, yes.. but you have to consider that the ice sword does not always hit from frame 1 because it is a projectile.
