Yeh, there's a big difference between 'Actions per minute' that AST has with target swaps, and 'Casts per minute' for stuff that is fast paced like NIN burst or MCH hypercharge windows, but they don't have to retarget ally/the boss twice every GCD. If 'Actions per minute' were properly tracked, including 'swapping target' in that count, I'd imagine AST's APM would be closer to like 60 65 compared to NIN's current 45ish

Look at Starcraft pro games and their APM counts. Now imagine that 'selecting units' doesn't count as APM, only pressing keybinds for the shortcuts to 'build another pylon' or whatever. APM count would be way smaller
