Hey Grimmy...no drainage layers for me. I used them years ago but then got lazy and the trees haven't missed it in my garden....your mileage may vary.
I really have no idea why I do just a habit and not positive as I have not tried without using the Fafard. It performs so well I may skip it. I find a handful of perlite and coarse sand gives me good drainage as is.
