Add a power attack button that consume 5 energy in 1 click. Afflict 5 times damage than single attack. Can also help HIGH ENERGY player to consume energy faster. It's so tiring to fight on the fightlist when you have a huge energy.
This has been requested before but my account get suspended so I posted it again :)
This will also be a good reason to add to health. Because you can easily get killed if you've been powered attacked.
