They should really give us a big buff to Mighty Guard as it's very weak tank stance..

Also give us FFXI Red Mage's convert

"Upon usage, user's current HP and MP values are switched."

"Amount of converted HP and MP will not exceed user's maximum HP and MP values. If the user has a lower maximum HP or MP value than the current value of the opposite stat, any "spilled over" HP or MP is lost."
