Final run of the week, putting me at 7 each of Ulduar and ICC, I picked up the Tonk and Boneshard. This means all I have left are the Ulduar Sanctum Cub and the Wicked Soul and Blightbreath from ICC.
Pretty pleased with my luck so far, 14/17 pets over 7 toons in 1 week. Also picked up a couple of garrison music rolls, and an assortment of xmog gear including 2 enchant illusions, plus all the gold income from vendoring everything...no Invincible or Mimiron's Head but we'll see what happens.
