Hi!
I've been comparing backgrounds in this game and noticed that some of them are seriously better than others. My main concern here is the Imperial planet background. Sure, they get some skills but they're at untrained basic level and the selection is more or less "meh". Further, they get a -5 on ALL Forbidden Lore checks. That makes the background unattractive for players in a game where it is very important to know things about cults, witches, mutants etc. In the core rules, an Imperial world character is best suited to be Scum or Guardsman since they get few Forbidden Lores. Psyker, AdMech, Assassin and Adept are bad choices due to the abundance of Forbidden Lore skills. Basically, there are few paths an Imperial born can tread and excel.
So how should I solve this? Remove the penalty on Forbidden Lore checks? Raise a few skills to trained level? Give them +5 on all Scholastic Lore and/or all Common Lore skills to reflect better education?
And on a sidenote: why do Volg Hivers start with Melee weapon training (primitive)? All classes get that training anyway, except Adepts in some cases. But Hivers can't be Adept in the first place, according to RAW. Should I remove it, perhaps give +3 to WS or maybe substitute it with Resist (Poisons) instead?
