This is my whole point. You can work around this "balance" by taking pool attacks instead of Super Strength. A better attack than Jab, a cone attack that does Haymaker damage.
For most melee sets, the Fighting attacks are a downgrade, this is why players keep suggesting Tough be unlockable without taking Boxing or Kick. I don't think Super Strength needs that level of improvement, just a little more parity. Make it a little tougher of a choice, like you might even WANT to take Jab.
