A four combo point Maim gives you enough time to heal yourself with a [Healing Touch], or gives your energy enough time to regenerate for a [Shred]. Also in 1 vs 1 you may have time to [Prowl] and [Pounce] again.
A low combo point Maim is great for interrupting casts.
Patch 7.1.0(2016-10-25): Now learned at level 63 (was 72).
Patch 7.0.3(2016-07-19): Total damage is now based solely on weapon damage.
Patch 6.0.2(2014-10-14): Now available only to Feral Druids.
Patch 3.2.0(2009-08-04): Tooltip now specifies that the Interrupt effect only occurs on non-player targets.
Hotfix (2009-06-08):When immune to the stun of following abilities, Maim, [Bash], and [Hammer of Justice] will no longer cause player spells to be interrupted but they will still interrupt NPCs. Also, when these abilities do stun a player target, they will not perform an interrupt effect and lock out the affected magic school. As an example, if a Mage is channeling Arcane Missiles and is hit by Hammer of Justice, Blink will now be available as the Arcane school will not be locked out as it was before.
Patch 3.1.2(2009-05-19): Rank 2 of this ability is properly considered a stun and can be escaped by [Blink].
