Blitz and all other abilities can be used during HEAT. While this may be a gameplay balance issue, there is a problem with a player who is not normally able to run to be able to not only go into a full sprint, but also do it so casually while being microwaved. IMO, if you're HEATed while blitzing, you should be capped at the walking speed. You can still be knocked over, but not this OH IM IMMUNE TO MICROWAVE DEBILITATING EFFECTS NOW magic. Also, hi from Japan.
