I just looked back over this spell and noticed the low duration.
At first, it seems like a great spell. Cast it on the tank/tanking-pet whenever you buff for group/solo, then go hunt, and it'll just help the tank hold agro, right? Well, yes, but for thirty-six seconds. Just 6 ticks. And, for those ticks, its only +5% agro, which, though it helps, seems a bit costly. You sacarfice two seconds (or four, if fizzle), plus the recast delay between normal spells, while holding still for the cast time, and 100 mana for a mere 5% increase in the tank's agro ability for 36 seconds.
I mean, a spell is better than no spell, since there may still be cases when it'd be useful, such as before a major pull when agro is hard for a tank to gain, 5% is a help.. even if not that much. Still, it seems to handicap an elsewise great spell. Should this spell have had a duration of 36 minutes as opposed to 36 seconds, it'd still be balanced.. I mean, after all, its a small increase in agro ability... frankly, a Haste spell provides more agroing ability than this does.
