PS I have done most quests in raid group, but i think it will be fixed.

You will have to complete some part of the storyline to be able to get Battle Krolusk and maybe unlock world quests.

I found that you don't need to do the WQ to get credit for the [npc=143249] portion of the achievement. Just round up a bunch of Faithless and ram them over and over. When you lose the Battle Krolusk, run back and remount it.

/way Vol'dun 48.48 35.15 Battle Krolusk

ok im an idiot. I was thinking i had to kill the mobs with the battle krolusk which was basically impossible since it did no damage. You only have to CHARGE the mobs, much easier
