I remember telling a friendAnd I think this is really the point to drive home, I think. If everything worked in the same direction, it wouldn't matter if we used ascending or descending AC. Have low rolls be good on the d20* and have all modifiers subtract- just as easy as it is today
"The problem isn't Thac0. It's that everything that makes your Thac0 better sometimes goes up, and sometimes goes down, and sometimes it goes up which gives you a number that goes down."
It is like a criticism I heard of 5e on a podcast today, it feels like different parts of the system was designed by different people who didn't talk until the end.
