Okay, I was thinking of switching my server's mod pack from mindcrack to the ultimate, but I have a question, what mods would I lose from switching (if any)? Sorry for being so lazy if you think I am lazy for not doing it myself!
If you click the "edit mod pack" button in the launcher, it will show you the list of mods for each pack. From there, it should be easy enough to compare the lists for Mindcrack and Ultimate and see what's missing, if anything.
