As I wrote elsewhere I went back to RM2/C after a long absence (~15 years), which was filled with RealLife and HARP
I decided to go for RMC, as I liked some of the enhacements.
After creating the characters for my new group we found that nearly all special rules for MA are missing in the new AL (like Weapon Kata, Multiple Attacks and other stuff), on the other hand I found that the Combat Companion is doing a totally different approach in adding these rules back to the game.
Though I didn't want to use Combat Styles (and the Combat Companion at all), I could pick some of the rules to allow weapon Katas. At the moment our Warrior Monk says he does not need anything special (as he is no Power Gamer), but I'm afraid that he would be quite weak compared to normal weapon combat (4 skills to improve, very bad parry, no magic weapons).
So, what are you doing/thinking? Are you using the old RM2 rules, using the Combat Styles or no special rules for MA at all?
