Mmh... I actually have my troubles with learning combos, since i never really played any other fighter and got cse for only 4 or 5 months. Granted Litchi's combos aren't exactly easy as well, but I'm just now at a point where i can do her combos consistently enough to think about learning another character.
I went through the archives here and people posted some tutorial videos that sadly got taken down from youtube, so I'll try if I can do some stuff from the combo thread. I remember from the challenges that I'm having trouble figuring out the rhythm of holding/releasing D while doing stuff with Carl. Maybe I will have a better feel for it now, since I have to hold D for Litchi's staff launch in some situations, even though its not as complex as Ada.
I believe one (or more) of the challenges I did used allecan, but I didn't do it from an iad - so yeah... gonna grind that a bit as well.
Thanks for your responses so far :)
