With the Glory of the Cataclysm Hero, I hit 17k Achievement Points!
I managed to solo a lot of the achievements for Glory of the Cataclysm Hero but I grouped up for a few of them:
Navimie, Corael, Aurii, and Crooked helped me with Crushing Bones and Cracking Skulls. Didn't remove all the Heroic Cloaks before hand so we were AoE Damaging by accident. We had to leave the adds alive so the boss could kill them We reset the boss and did it again easily.
Nathamanz was with me for Straw That Broke the Camel's Back and Kill It With Fire!. We just DPS Earthrager Ptah down while avoiding things that could dismount us. Then just waited for the Burning Souls to appear during the High Prophet Barim fight and killed them.
I Hate That Song took several attempts with a few groups, including an attempt with Nathamanz again which didn't work out. Muppeteer (Vinyl) and Chihako were with me when we finally got the achievement down. Navimie was in the group for a few of those attempts before having to head off.
The strategy that worked in the end was this: I ran down and agroed all the snakes then ran up to solo the boss. The snakes wouldn't respawn because I didn't kill them. I used single target on Temple Guardian Anhuur. Vinyl and Chihako then stood at the switches and used them when Temple Guardian Anhuur started to sing.
