No, LotM is a terrible spell including the self-damage, because it is a waste of time in terms of throughput and HPM. It's only use is A: people require heals and there is movement w/ no other available instants, B: someone will die in the cast time of an FOL.
Especially if you use faith, then LotM is basically worthless.
To keep on topic, @
Caramuru: Here is my most recent log from H Xavius
https://www.warcraftlogs.com/reports...ling&source=10
I'm 2 ilvl above you and w/o a legendary at the time of this parse.
Main differences:
1. You use LotM far too liberally, stop.
2. You can see that I have more FOL casts added into the fight than you used globals on LOTM, and my fight is shorter than your fight. What does this mean? It means you need to use your mana, and FOL is the most effective way to dump mana.
3. You don't use LoD or HS enough. I have more casts of both in a shorter fight.
4. Why are you casting 33 holy lights in a fight when you have over 1million extra mana to burn through? This goes back to 2: Plan your mana usage.
5. Mercy is not very good. Sacrifice is generally better if you can get away with using it on a fight (especially with the legendary shoulders converting the extra damage taken into healing.)
6. You could've used twice as many bestow faith in the fight. Hint: even with twice as many bestows, my arcing light still did more healing with higher overhealing, with less uses. Xavius is a good fight for LH due to stacking and general raid damage.
7. I am terrible at using Tyr's Deliverance, it is known.
8. Based on me doing 70mil healing to tanks vs your 76mil healing to tanks, you either pumped them with LotM (inefficient) or you hardcasted on them a lot (waste of time that could be spent dumping your extremely excessive mana).
9. Why do you have a fifth healer who is being outhealed by tanks? Even accounting for his active time, that's sketchy.
10. Oh, you are 5 healing a 18man raid. That would explain why there is so little raid damage to heal. I was 4 healing a 22man. (There still wasn't anything to heal, i had 50% overheal o.o).
So, overall I would say that I am slightly impressed that with that much LotM you still have a relatively good log in such a small raid. But in any case, you can improve through the points I listed above.
