I have seen quite a few MM builds including this talent lately.
Increases agility by 2% and intellect by 6%.
Assumption: A typical blue geared lvl 70 would have like ~450 agi and ~200 intellect.
450 * 1.02 = 459
200 * 1.06 = 212
Paired with Careful Aim, 12 * 0.45 = 5.4 attack power.
9 agi, 12 int and 5.4 ap.
Unimpressive by itself IMO, and even more compared to +8% crit chance
in imp. Barrage (for the same 2 points).
Or?
