MP5

MP5 (also known as MP/5) is a shortened term for the attribute that is itemized as "Restores X mana per 5 sec." or "Mana per 5 seconds".

History
With World of Warcraft: Cataclysm, MP5 was removed from gear and replaced with Spirit. To accommodate this change, all healer specializations received Meditation as a passive ability, while caster dps had their active and passive mana regeneration rebalanced appropriately to no longer need nor benefit from a mana regen stat. MP5 was still present on certain redesigned player buffs throughout the expansion, though these have been removed since.
