Giving your vote can be a good thing anyway. I too would really love combined rules but I have no idea (yet) how to implement it cleanly so I put my hope to Solar - he too has discussed this functionality iirc.

As you probably know there is this workaround though:

./john -w:wordlist -rules:best -stdout | ./john -pipe -rules:leetspeek hashfile

This accomplishes the exact same thing but is not resumable. You could of course make it resumable by letting the first process produce a temporary output file instead of piping it, but that file could get mind-bogglingly huge. On the other hand you could get rid of some dupes by throwing unique into the mix:

./john -w:wordlist -rules:best -stdout | ./unique templist && ./john -w:templist -rules:leetspeek hashfile
