It's funny how well-regarded the RC mass warfare rules are. When I used them in practice (like running module X10) I found them very poor in actual play. The premise is great, but the way points are added up for armies totally doesn't simulate how actual D&D fighting occurs. The disconnect was too much for me to deal with. (And same for the dominion rules when I used those as written back in the day.) So for me, those are actually negative points to the RC.
