That's understandable, and it's all because of the Jump Cancel mechanics, I had the same problem with Bang's "Crash & Dash" combos at first. You still play CT right? Just for practice anyway? Practice Ragna's basic ground-to-air combos until you get them 100%, that's all the advice I can really give. Or you could try Bang's Crash & Dash combos to get a firmer grasp on timing, because let's face it, ragna doesn't really have the strictest combos.
