combat is too hard? lol
Some newer players looking back onto AD&D 1e or B/X D&D, are unsure how the combat system works. Maybe because they are used to the way the AC system works in 3E and 4E. Their system is ascending for better while old school is descending for better AC. The question I often get is "how do I know if I hit?" Well in 1E, players were not really allowed the information of the "to hit" numbers, thus why it was printed in the DM Guide. Players were only to, roll add or minus whatever number, and tell the DM. The DM who had the AC and the to hit chart would compare. B/X gave the players a little two hit chart they could see when building their characters, so players had an idea that what roll would hit what AC .
So I guess its up to the lazy DM to enforce the proper rules..
I believe the reason the various hit charts slowly went away as the editions increased was to make things simpler for the DM and the players. I know with 3E and the D20 system they were trying for a faster combat system and one that a player or a DM could easily figure out if it was a hit or a miss. I don't think it really made it any easier, it just made certain classes "boring" to play. Such as a fight became so boring, as they had one great thing going for them, they could jump into battle and beat the hell out of things, hitting more then everyone else, but the "one hit system" 3E introduced took that away. Now a wizard or rogue can hit just as easy as a fighter can.
All I can say, is oh well. Long as you have fun, enjoy. Don't bash my system I grew up with, that was "rules lite" because you don't understand it or think D20 rules are better.
