As long as it generates a log like ACT does that we can break down and look through. The most useful thing of ACT is the logs it generates. You can't improve or really know what those numbers mean with out going through the logs. You can stare at the meter all you want during a fight but you can't hit a magically button that fixes your mistakes. You can look at a number after the fight but you can't do much with knowing that number. Only once you can break down the log and look through everything from the fight and see where you can improve does any of this matters.
