I have successfully produced drum tracks without a drummer. And the good thing is that the tracks are still playable live with a real drummer. It is just recorded without a drummer. With these type of set-up i get these following benefits:
a. No need to spend long hours in recording studio which translates to big recording budget.
b. No need to argue with a hard headed drummer.
c. No need to risk with out of timing drummer.
Unlike other drum sequencing, I think this produces the best sound. Try to hear one of my produced tracks using this type of drum sequencing method:
