Judging from your kill (the seven attempts link):
1. You didnt use 2nd old war pot -
I always pot twice unless someone pulls early
2. You didnt get advantage of shield of vengeance, you could pop in when soaking the melee pool for additional damage -
Will start doing this
3. Use 375 haste food, not 300 -
Easy fix
4. You didnt get additional crusade near the end which means you didnt use it on cd -
5. You used vial on pull without any crusade stacks, use it when you're at 15 -
Thank you for the advice
6. Use arcane torrent if you are a blood elf -
Thank you for the advice, rarely have a holy power issue but this will help
7. And last but not the least you wasted WAY too much holy power, like 1/6 of what you generated. You should really improve that part and it's probably what caused the low parse in the end. -
See below
Also, you don't need to cleave maiden and avatar all the time, you can do that during cleansing protocol but certainly not the entire fight as its not a real benefit for your group... orange parses are absolutely achievable without cleaving
Good luck
