Using skills recklessly without a clear purpose is a waste of MP, especially after Lunar Crowned. When a person's Mana reaches a critical limit, it affects their motor skills and vision; blurring their sight and causing temporary loss of balance – ultimately leading to death.
One can still maintain their Mana limit using Auto-Attack MP Recovery, but if the percentage gained from this auto recovery isn't sufficient, it's as good as having no benefit. Essentially, Auto-Attack MP Recovery only adds a minuscule amount of MP randomly, unless supported by a skill that enhances this attribute.
The Samurai Class heavily relies on MP for powerful attacks – relying more on skills than physical strikes with a katana – and MP management often posed a problem for Soran when he first learned the class.
