And which variables would those be exactly? The stamina gauge is gone. That means the value that each ability had, to subtract an amount from the gaugebar, is gone. In some cases the cooldown value, for delay, of an ability is increased to compensate for the lost stamina gauge, which could have added an additional delay in the old system.
The tp-gain from abilities, besides the default auto-attack, is either a bug or a new feature, but it has nothing to do with balancing auto-attack.
Tell me, besides those 2 values for each ability, from which one is deleted, what other variables would be affected?
/em is kind of dreaming of a SE developer to pop up on the forums and give a lecture about how they did it.
