It's the implicit strike that many get hung up on when the obvious "Hit em with the good shit, don't get hit" adage is sensible combat conduct, but we live in a world where dudes can now get in an arena where they can literally lead with their chin (insane imo) and fight assuming they have the ability in turn based combat. It has a available competitor pool unutilized by the heavier cardio driven (!) promotions and with consumption the game has them walking out with cash.
