When you fight in Time you have to be at the top of your game all your knowledge of your character is put to the test. Fighting the gods in Time is very challenging if you make a slight mistake it could mean the raid wipes.
We had a slight shortage of healers on out last Time run all the way to Quarm we started losing people quickly and I was not sure we would make it then I got battle rezed in and saw that Quarm was at 14% so with rez effects on ran to the dragon started swinging hoping we could kick it's ass. I was very conservative at that point turning off attack only when Quarm turned toward the dps folks. Then he fell and it was awesome our healers did a fantastic job and in the end it was great to be apart of the family again.
Just a side note when loot if being handed for Quarm do not attack and kill the egg, some fool did that on our last raid and we almost didn't get the loot handed out.
