BnB= Bread and butter, it means your regular combo you use all the time to punish, randomly hit people with/whatever your hearts content, it is essentially your combos that you just use constantly, like kenshis bnbs are B32 (or F32 if you are punishing someone) run cancel, F32, telefury. Vortex is putting people in a guessing situation where they have to guess weather you are going to hit them with an over head or a low and after everytime they guess wrong they get put into the same situation where they have to guess again
F22 is not a vortex, that can set up into one, however balanced kenshi has no mix ups, vortexes, etc. kenjitsu has some, but they are not very good, also the best way to get that opener off is to mix it up with a lot of grabs and 4D4, then once you hit them with enough of those and trained them to block high then you can hit them with a B32 opener into run cancel F32 telefury for a solid 31% damage
well the better option is to use F32 since it does more damage and pushes them further back. but as a combo starter put in b1 and then immediatly cancel into RK
