Possible issue: Disparity with Living Dead and tank max HP

[Sylve]

As a healer, there are a few ways that I deal with Living Dead.

1.) WHM: Benediction - this is the only way that will instantly clear the debuff.
2.) WHM: Pre-cast Regen (timing based on how quickly the tank's HP is going down - usually estimating ~1GCD before the debuff occurs) > Tetragrammaton > Afflatus Solace > Thin Air > Presence of Mind > Swiftcast (optional) > Cure II until debuff is cleared
3.) AST: Pre-cast Earthly Star (timing for Giant Dominance on detonation) > Lucid Dreaming > Diurnal Aspected Benefic (same as WHM Regen timing) > Essential Dignity > Lightspeed > Essential Dignity > Swiftcast + Benefic II > hard cast Benefic II until debuff is cleared.

SCH I don't really play often, so I don't have a good answer for how SCH can deal with the Walking Dead debuff. Obviously solutions 2 and 3 are... less than ideal, but they do work with a relatively high degree of success.

Planned Living Dead is easy. Excog -> Recitation+ET+Adloq -> Lustrate to finish. Excog is 40k~, ET Critlo is 50k~. Most of the way done just with those two. Then a Lustrate and maybe a Physik if required. Union too.

For unplanned, like overpulled trash its much the same as above. I tend not to waste Recitation on trash early in a pull since its usually the latter half of the pack that gets dangerous when Tank cooldowns run out.
But I also do not use Energy Drain, ever. So I always have some AFs to burn when required. In the event of the fan receiving an inordinate amount of fecal matter, There's always Dissipation and triple Lustrate. We have 10 seconds to deal with it, and theres a LOT of healing we can do in 10 seconds. Worst possible case is none of the above available and we still have Dissipation into Physik -> Lustrate -> Physik -> Lustrate -> Physik -> Lustrate -> Physik. At around 15k~ per Physik and 20k for each Lustrate, just that is enough to clear it off.

Its really not hard.
