Here's an example of when using rudder to 'pick up' a wing is a great idea....when being aerotowed in a glider.(in the early stages of an aerotow the ailerons are useless) But the rudder will pick that wing up straightaway. and of course energy is being added.
Another is: when a stall is about to kill you and only the rudder is still working. The ailerons are of in a huff for sure, but the roll spoilers?
