My evolving rule of thumb for combat without the tables:
1* use Mongoose rules (or similar) to grant stat bonuses.
2* add an Ergonomic DM to each class of weapon.
Those two combine to form a single Attack DM for each weapon, and in effect they replace the advantageous/disadvantageous weapon DM table.
3* add an Effective Range value to each class of weapon.
This one attempts to replace the attack-by-range table. It's not there yet, but it's a start.
4* rate armor in AV, typically from 0 to 3.
This is essentially the to-hit DM for having armor.
The attack task then becomes:
Up to Effective Range: 2D + Attack DM >= 8 + Range + Armor.
Beyond effective range, DM-2.
