Nine-L I have a similar problem with DNS attack inputs from 1P side. It owes largely to how I hold the D-pad. With practice and over-doing the motion(try to start your motion say from 1 instead of 2) you can decrease the side-dependency significantly. It also seems like changing thumb placement on the d-pad can help too, but I won't get too much into detail with that since its probably a person by person thing anyway.
Paragon. It's still somewhat early to be getting to tiers I think, not only has the game been out for only a couple months, but it was patched recently too. I suspect that when the dust settles Ω will be a high-mid tier character like sophie was in IV, running train over unsafe lower tier characters with her powerful punishment game and having to work significantly harder versus characters with good movement, general poke safety and block mix-up potential because of the strength of the guard button against her. I don't think she can be lower than mid tier because she hits too hard and solid damage output almost uniformly makes a character viable(for example SC IV Cervantes).
I'm not sure how jG will play into all that though, she appears to be a character that can take advantage of more jGs than other characters can, owing again to good punishment options, but might be somewhat susceptible to random jGs herself.
As for 4K I don't think very much of it. The reward is too low for use outside of CH and i20 linear highs aren't really the prototype of a good CH garnering move. However, Bean has in the punishment thread a couple situationally useful places for it from what I gathered skimming his posts.
