for those that don't know what this skill does it basically lowers the agro associated with magic spells to keep you from dragging mobs of tanks.
for an enchanter I think the skill is a must have, same for shammy and clerics since they have ways of getting mobs mad at them, and when the adds come they have abilities which could get adds mad at them when the adds arn't being proprly controlled. It probably will be usefull for wizzy as well so they can get away with harder nukes (never played them)
it isn't so much that this skill is used in often in a perfect xp group where nothing goes wrong as it is that when the skill does come into play it is usually life or death. As a cleric when I see two mobs comeing at us and I know we don't have a mezer I am glad that I have the ability to cast those nessesary heals without getting stomped on by the adds. Think of this as a 'when things are going bad I can do what I need to and still be safe' ability.
for a necro solo kitting don't worry about it affecting your kitting abilities; your still out agro you pet by more then enough so long as your pet isn't taunting. However if you are in groups where your kitting while group DPSes then you may have trouble holding agro from the other group members. Not sure if this is a real concern or not as my necro is still not too high and dosn't end up in kitting groups much.
Since it is never in an enchanters best interest to have agro, I would say it is certainly a worth while investment. But what about necros? When grouping, it takes a great deal of effort not to steal agro when doing 1.5K damage a tick with dots. In that situation this would be a nice AA to have. But when soloing, agro kiting is the steak and patatoes strategy at 65. I'm worried this will let my pet steal agro, and with no way to turn it off or undo it, this could permanently cripple my chatacter.
I was just wondering if this ability is worth investing in for a Enchanter that hunts alot in PoP zones. I tash and slow virtually everything we pull but don't wanna waste my AA in this if it doesn't seem to work.
