Its just kind of in our psychology to think of overheating as "bad." Like we aren't supposed to do it. If they called it something like "Overdrive" or "Overclock" I'm sure it would do a bit better to wash away those fears from newcomers. Overheating is good, as long as you are doing your best to squeeze in every drop of damage you can in your overheat window. You can get away with avoiding it if you want, its just not optimal. I would practice on a dummy or two however, once you get used to the overheat mechanic it isn't so scary, i just wish it were a bit more forgiving at times.
