Various foods aside, this is still nagging as an issue for mages who want to cap out non-offensive magic skills or melee who want to work on defensive skills. No matter what, it seems that skills like Enhancing Magic (essential to Red Mages' survival), Healing Magic (which will mean something soon, if Camate's words are good), Guarding, Parrying, etc. continue to move at a glacial pace.
The question I have is whether there's a reason for the slow rate of skill increase in these particular skills while others increase at a very reasonable clip. I'd also like to know if there are any plans to address the issue.
