I do not want to see potion chugging in any game ever again. I played RF Online and Aion. At that point the devs should just remove the resource and make every skill infinitely reusable because that is exactly what happens. I hate having to constantly buy and chug potions nonstop. It makes no sense thematically. Mana cannot come from drinking sugar water.
That said resource generator skills make no sense either. How does casting a skill increase the amount of mana I have while casting another skill reduces it? Shouldn’t every skill reduce the amount of mana I have available? And shouldn’t mana regenerate passively and also be Concentratable to empower spells ala Dragon Ball Z?
