i practically transcribed the combo section from the JP wiki since it overlapped with a lot of my own combos. they listed every combo starting with c.C cause it does the highest damage. if you think about it, cr.C does 70 pts of damage, while cl.D does 40+45 pts of damage. you'd probably think, "hey cl.D does 15 more pts of damage!", but because cl.D is 2 hits, it affects the scaling of the rest of the combo (at least JP wiki denotes so). i'm sure the difference is very minimal. i agree with you though, for ease of use, i also use cr.B> cr.A. cr.C is definitely not practical as a combo starter. i did, of course, add that combo starter section so i hope people reading the wiki definitely don't take cr.C as the staple starter. maybe i'll change that in the future.
also, the JP wiki notes that HD combos do more damage if you use far C or far D, but i find that kind of hard to do in actual matches lol
did you want me to put up the wallcarry combos?
