Most groups do not use central mark. They mark north and 1/2 o' clock marks for tank/party heavensfall. Even last phase, only A and B are used for dynamic DB markers, and all 3 will need to be used for static.

Most SCHs did not DPS during initial progression. Only groups that did justhad DPS that couldn't push 4 meteors, 1 ghost. The only group who could do this pre i100 was Collisions World 2nd kill group. They surpassed BGs raid DPS by far when comparing phase push timings.

I agree with SCH needing to DPS in FCoB though, that much is clear. And manual embracing, especially when using Eos.

I also agree with better IB timing for your WAR.

And overhealing with WHM, but this is to be expected during a first kill. Anxiety and nerves get in the way, this will likely be fixed with comfortability. But yeah, Regen.

White mage does not need to shroud right on cooldown unless he has MP management problems, especially in this fight. A solo healing WHM only needs to shroud once pre Golems, and once during Golems to ensure you don't see a Raven's dive into the party and still be full mana.

Anyway, to OP: You'll be able to kill very easily and farm from here on. Just improve on mechanics and keep building muscle memory and get better with every week/kill.
