And Orks used to be able to take up to three specialized weapons in a squad, could take power weapons (burnas) in regular Boyz mobs, could reduce saves of better than 4+ down to 4+... Oh, and they also had power weapons for Nobz, but I think that was only in the lists that were released with 3rd edition and the playtest list that got leaked, but you can still see them on the Nobz models.
Or heck, let's just go back to 2nd editions. Orks had WS3, BS3, A1, much more access to ranged weapons, an entire unit that infiltrated and had power weapons...
So yeah. Times change.
