Tips for SCH in T5

[NintenPyjak64]

It's your other healer. WHM can deal with a ton of the damage easily minus a few situations where having a SCH is mandatory. What I would suggest helps out the group as a whole is Succor pre-fireballs, Aldoquim MT before Death Sentence, Lustrate after Death Sentence (Infirmary Debuff makes WHM useless until it wears off.). During Snakes I'd say is a good time to use Eos's healing potency buff as well as her AoE regen.
The last time I ran T5 our SCH (pug) didn't have Aetherflow stacks during Snake Phase and since I used Benediction earlier in the fight it wasn't available so our tanks dropped dead. Be sure to never waste Lustrate on party members unless you absolutely have to. Aetherflow comes back up every 60 seconds and DS every ~30-35 seconds meaning 2 Lustrates after DS and 1 for Sacred Soil or Lustrate on 1 other party member. Considering the interval of 45 seconds between Divebomb 3 and 4, there's really no excuse for not having 2 stacks at least (Sacred Soil for last set of divebombs to minimize healing at that segment) so if your WHM focuses one tank you can easily keep up the other until after 2 hour where healing becomes easier

Don't take everything I say for truth because I've never done SCH in T5, I'm only talking as a WHM that has never partied with a competent SCH in T5 (which is why I don't have a win yet)

And last thing I'll say is that SCH is not a WHM. You're a proactive healer that mitigates damage more then heals HP. If you're healing 80% of the time your WHM needs to step up their game.

I would have to disagree on this. When running WHM/SCH, the WHM is actually key in conflag phase. The WHM should be the one casting SS before DS and applying a C2 just as it hits for full strength. This will leave the tank at or near full HP for the incoming plummet or auto attack pre lustrate. A SS/C2/Lustrate is actually overheal on DS. While I love working with a SCH I have also done WHM/WHM with very little issue. The only time of the fight I will actually leave DS healing mainly to the SCH is in the last phase where I take care of the rest of the party with Regen/Medica 2. Now with all that said literally a 2 seconds hiccup in your timing on either SCH or WHM and a tank could die.
