As for Strength I'd have to read up what SB actually does aside from melee damage bonus before I'd cast my judgement there. It may well be possible that Unnatural Strength actually works fine - Unnatural Toughness, however, confers too much of an Invulnerability bonus. One that is not backed up by the fluff and one which trivializes many potentially fun encounters. Surely you have to agree that a Marine's naked body should not rival his own power armour in terms of protection?
Actually YES, the SM naked body HAS to rival his armor in terms of protection, because that is also the case with normal Imperial Guard grunts. Why should SMs be any different?
If you change this you might as well also change the whole way TB works, or only allow TB to apply to damage reduction when you have armor on, or something like that.
Hmm I wonder how the game it would be if a SM only had about 10 damage reduction total vs a Guardsman's Lasgun? Would they still be able to fight off numerous guardsmen and still win? The problem with it is that Stormtroopers are already at that level with their carapace armor+TB already.
