[QUOTE="guachi, post: 7091590, member: 6785802"] I never found descending AC to be complicated. If only because using "class" to describe a quality of something has historically meant lower is better whether it's first class mail or a first class petty officer. But even if I didn't, all THAC0 does is use subtraction instead of adding. The problem for a system isn't subtracting or adding, it's subtracting or adding large numbers. Specifically for subtracting, it's subtracting where the difference is large. At least with THAC0, once the difference grew to 10+ you either automatically hit or automatically missed basically every monster there is as almost no creature had an AC above 10 or below -10. In that respect THAC0 is easier as you can easily discard certain values out of hand without having to do the harder math (where harder is where the result is greater than 10). For a system of ascending AC the difficulty in the math comes when the bonuses are high. A '+ to hit' of, say, +27 makes the math a little more difficult than if the bonus is +7. For me as a DM the problem isn't THAC0 or + to hit. The problem is actually remembering what the THAC0 or + to hit of the monster actually is. I spend far more time looking those up (usually a few seconds) than I spend doing math (usually fractions of a second). Heck, I can do the math for either THAC0 or ascending AC in the time it takes me to say "I hit AC..." So in that respect there is not a lick of difference between the two systems. [/QUOTE]
