In effort to bring the plasma and melta weapons more in line of what they should do (especially compared to bolter), I am planning to change them in following ways:
Astartes Infernus pistol add Felling (2) quality
Astartes Meltagun add Felling (2) quality
Astartes Multi-melta add Felling (2) quality
Astartes Plasma Pistol add Felling (1) quality
Astartes Plasmagun add Felling (1) quality
Astartes Plasma Cannon add Felling (1) quality
When combined with Volatile, Maximum Setting (plasma) and Short range damage bonus (melta) this alone should be enough to make meltas and plasmas actually better bolters... as they should be.
This rule is totally nuts. I will either use the DH's Righteous Fury or I'll rule that every rolled 10 is eligible for re-roll. But not the entire damage. That's just silly.
