Just wanted to cover a small point that never sat well with me in DH1.
Thrown weapons with blast, like grenades, scatter 1d5 metres when the attacker misses. This means that unlike normal weapons, when you miss you still have a chance to hit.
For example, frag grenades with blast 3 are still going to hit 60% of the time on the primary target when missing and web grenades with blast 5 can't miss (unless you get a jam effect) no matter the attackers BS score.
While I understand that to a certain extent grenades are supposed to be easier to use for unskilled operatives and there are some advantages to the defender from a scattered grenade (like possibly being able to dodge when you couldn't at all before), it seems to me that it would be better to take into account the attackers DoF in the scatter, making it 1d5 + DoF metres scatter.
This way when attacking, a novice (BS 27) rolling badly (attack 91) would scatter 1d5 + 7 metres, unable to hit the target at all. This would make grenades in the hands of someone unskilled much more of a liability and a skilfully user of grenades much more of an asset.
