Arrrgh! Had a huge reply written and lost it. You may now find my answers more brief.
iwatt said:
1) What are the effects on EL for well equipped units?
Most likely, no effect-- unless they are
very well equipped:
A PC's gear is worth 0.2 CR per character level.
An NPC's gear is worth 0.125 CR per character level.
The value amounts for "Wealth by Level" are available in the DMG.
EDIT: I actually used this function to set some of the CR/EL/BR ratings of the units that are available to the PCs in
Slavelords of Cydonia. It's a simple thing to knock .2 CR off a unit if they are under-equipped, or add .2 CR if they are well-equipped, and then recalculate the Battle Rating. Obviously, it has a greater effect on low-CR combatants than high-CR combatants (ie, relative to what percentage of the total CR is represented by 0.2 CR).
EDIT: Of course, if you had a 10th level character stripped naked and forced to fight, that 0.2 CR per character level would knock a full 2 CR off his total.
EDIT: But as a general rule, if your "conscripts" have leather armor and a club, and your "elite footmen" have a chain shirt and a longsword, it's not going to make a difference.
2) What combat scale do you recomend (i.e unit size doesn't become to unwieldy for Command Checks.)
Unit size should be set to the same size as the smallest unit involved in the battle (generally speaking).
3) For combats with different sized creatures: why not use same size counters but large creatures have 1/4 creatures per unit than medium creatures? Maybe this would make the units more balanced when base CR of dedicated units are to different?
This was one of the longer answers I lost. I will sum up: If you want to do it, you're on your own. A good deal of mathematical R&D went into the rules that I wrote, which assume that most folks will use miniatures or counters that are properly scaled to size.
4) What are the effects of conditional modifiers like a Dwarfs +4 to AC against giants.
No effect. A dwarf's bonus vs. giants is already included in his CR. You should strive to avoid accounting for ANY function of combat that is inherent to the creature, as opposed to being a function of terrain or tactical position.
5) I don't see the effects of facing in your rules. I guess yo mean that units can only attack those they're facing? do they still get a counter-attack if not facing the attacking unit? Is there flanking? This actually is the most confusing part for me and I rather hear from you before delving into rules tinkering.
Read the section
Battle Actions: Move again. It's all there. To summarize, facing affects movement.
Flanking is not accounted for per se, but it is accounted for. I'll refer you back to the first long Q&A post of mine in this thread, page 1.
