I don't like ogryn. I don't think they fit in a group of non-ogryn and I think they are broken with UT and US. Anything I throw at the humans bounces off them and anything that can hurt them tpks.
I will admit part of this is because I let a character craft armor for him out of a literal ton of shovels (I was a young GM with such wonder in my eyes) does anyone else have a problem with them either in the fluff or for balancing encounters?
