This post may be a bit difficult to explain, but I feel it is a very bad idea to make all individual skills in the game using MP.
Although I do not have experience as a Mage and have only played as a Hunter, I know that near current early mid-game no one will rely on any of the Skills they have acquired other than regeneration due to how much Mana moves cost to use and how slow it is to regenerate.
I feel it would be much more appropriate at least for physical moves like the Hunter’s blade throwing skill to use Stamina instead of Mana, or just relies purely on a cool-down system.
I feel the only skill anybody who isn’t playing the Mage class is Regenerate.
I’m interested to hear peoples thoughts…? I feel skills need to be vastly buffed or the cost drastically reduced, or an entirely alternative system to manage their use.
