Lack of weapon variety

As much as I am enjoying the game right now, i am level 25 as ogryn and the progression is very rough. all i got was a heavy stubber at 25, when all my fellow rejects get all sorts of lasguns and swords and staffs and chain weaponry at around level 14. I hope there is at least some interesting weapon variants in place, because the ogryns arsenal is a little lackluster, even on the variant side.
