Healer design is still terrible and I'm tired of apologizing for it.

That’s pretty bad - hopefully the last savage fight requires some gcd heals? Not sure if this tier is comparable to the e1s tier at all in terms of difficulty?

If they feel like they don’t want to put pressure on the healers in fights, they could give instant rez’s to the tanks and then vastly increase the incoming damage?

I can assure you p4s door boss slaps the party a lot and pretty hard in some situations. P4s phase 2 has actually almost no healing until the curtain call mechanic were you have too break 8 tether that deal raid wide damage in a specific timing. Healing wise this raid tier is actually pretty relaxed. Also pretty sure they use some gcds for p3s because fountain of fire phase deals for every tower you soak tower 99 % hp dmg too the healer soaking it (you have 3 tower and both healer are on opposite sides doing that).
This raid tier is really pretty heal friendly still. No Titan maximum stuff
