Was messing around in training. The same wake up attacks that can punish F4,1,2 ~ Reptilian Dash (whiff), F4,1 ~ force ball also punish F4,1,2 ~ Reptilian Dash (whiff), F4,1,2 ~ force ball with the only difference is that for F4,1 ender you must roll while the F4,1,2 ender cannot be rolled if you want to punish. Essentially the F4,1 ender is good against people who don't know about the roll thing or can't do it consistently but you can also mix up the two options to check the opponent's reaction times (one must be rolled to punish, the other cannot be rolled or it won't punish at all).
Cancelling either into EX force ball, EX Acid Spit, Invisibility, or the Noxious thing cannot really be punished by anyone except an extremely specific situation involving Ronin Takeda (which nobody plays).
