Corner combo info? is this new to AE?

last night i was messing around in training mode and i did this and im not sure if its new to AE or if i missed the boat completely in super

i did this

(corner) focus attack EX rocks standing HP c MP hk ruffian then ex criminal upper and all the criminal upper hit, no fadc nothing,

it did about over 400 damage but there are other combos that do over 400 damage with no fadc, this one uses about same meter.

is it character specific? is it worth to do, or is it one of many styling combos cody has. Discusss

it works on almost all characters with a few exceptions. you can also use to reset them, or do a mk/hk ruffian.
