well.....actually the current HTB skill for fighters/swords is like a spirit bomb ....
i think they could do the same but with a bigger energy ball and with a casttime
or we have to press space as fast as possible to increase the energy ball and dmg....or the mouse (when you get knock down you have to move the mouse too)
and as i said it could be HTB3 for all classes which you have to wish with dragonballs...
