f212,1+2 can be ok to start with for easy mid-damage (follow up with red dash-upslash-jk-teleport drop for easy ~30%) but I wouldn't get used to it because of how long you can get stuck if something goes wrong. The biggest advantage of that string, to me, is that a lot of people still don't know theres a overhead at the end.
She takes a lot of work. The awkwardness just takes time, you have to be more confident with the combos and daggers. There are interchanging pieces to her that you need to have down so you can improvise. Every time I've leveled up with her, its been frustrating and I never really saw the fruits until the next day when it became more of an instinct.
I know people have used this analogy a lot for other characters here, but she really does remind me of Akuma. The red dash is her demon flip, her kunais are the air EX fireballs to cover the approach. She feels like she has lower health in a sense, because you're going to be harassing them far more then they are to you, in order to do the same amount of damage until/unless you land a giant combo to remind them whats what. Like Akuma it doesn't always feel like you should be focused on zoning, yet you end up having to zone in order to make openings. The only thing missing is a monstrously damaging x-ray.
