Try the mipsbe torrent, it seems to have all the files you are looking for.
http://www.mikrotik.com/download/router ... 18.torrent
I normally just use the routeros-ALL torrent to get them, but Mikrotik might have forgotten to add the all_packages_mipsbe section this time.
Which packages do you use that are not included in the combined package?
A few of my routers need ntp for ntp-server, and I have 1 or x86 routers with UserManager. But almost all the rest don't use any packages that are not included in the combined package file.
