The Tedium of Assualts

[Poor Yorek]

I assumed it was column shifts because that is how all mods to combat are done in the game.

Well, not all since AT fire mods are to die rolls, but certainly DF/BF/assault combat mods are since the tables are truncated in terms of die roll results - i.e. no 13+ as in the AT table.

I just offered the die-roll interpretation - though perhaps "option" would be a better choice of terms - for the reasons stated above; it is almost the same as the col-modifier approach, but just a bit "softer" for those who might prefer that.
