As a general rule of thumb, basic attacks (Slashes, jabs, etc.) should do 1-10 damage, heavy attacks (Attacks that have the users "full force" behind them. These attacks, if missed, would basically ensure that they won't be able to block or dodge of the opponent counters. Similarly, after taking a heavy attack, the opponent won't be able to immediately counter.) should do 11-20, attacks with set up (two or more posts in the making, ie setting a trap and then the next turn activating it and using it to empower your attack) should do 21-30, 31-39 should only be achieved through combos, with the total ending somewhere in that range IF all attacks hit OR, as mentioned above, a heavy attack with set up. Anything 40+ should be either a team attack or SERIOUSLY detrimental to the user.
