Hey there, long time lurker on this site. Been playing Ragna since CT days and I love how much progress they made with this character, when they finally PACMAnized Dead Spike, my day was made. But anyways like Titanium Beast said I'd rather have him be more interesting, than just simply improving his damage. Ragna and Jin are the closest to strait up fundamentals characters that you can get in this game to me anyway, and he's the reason I keep playing this series.
Ragna seems to be pretty close to balanced at the moment, but I'd personally like to see 2C's advantage go up to +2, a little faster startup and less pushback on 5c, 5d, and another overhaul on his 6D. I personally don't mind the 6D floating the opponent, but I think it would be interesting if you could use 6D as a frame trap for once, perhaps by decreasing its startup. Of course with the change you could shave a couple frames of blockstun off of the followup to compensate.
For Blood Sycthe, I'm not really sure, perhaps faster startup, and having it hit high, I kind of like the arc it covers, its like an anti air bait, but its too slow for general use. Last thing I'd want is a j.6d with a sycthe animation that hits directly in front of him, kind of like Jins current j.C but less range, this way he have a way to control a piece of space, he currently can't and 5D, 2D gatling lol.
Other than that I'm somewhat ok with current Ragna, I actually like how you have to get your opponent closer to the corner to get big damage, rather than doing the same thing all the time, makes feel satisfying when I pull off a 623d combo close to the corner off of overhead or 5b.
