Tanks Pulling Trains (Who's Wrong?)

[Karthunk]

Today is the first time I've been yelled at for not keeping a tank alive in his massive trains (Dohn Mheg).

The DPS lectured me that I should be spamming Holy instead of heals, and the tank accordingly blamed me for his deaths because of it. I know that wasn't it because the tank died in 2 globals and the packs lived far beyond 3 casts (diminishing returns).

So we either wiped because:
a) Cure II spam wasn't enough to keep the tank alive (and I mean literally button smashing)
b) I ran OOM before the packs died because (a)

Am I at fault here, or is this guy just not using cooldowns / pulling too much?

You need to do more than just spam holy on the first 3 casts. You have a 4 second, 2 second and then a 1 second stun for the first 3 Holy cast. Be sure to weave in OCGDs and GCD while the entire pack is stunned. After the first 3 you should have things in order that can freely cast Holy.

Asylum is your red light for any good tank. If they see you put down Asylum in front of them they should stop there. You need to be right up the tanks butt when they are doing large pulls as well. If you are 2-4 seconds behind the tank then you are at least 1 GCDs + 2 OFCDs behind on the pull.

Pretty much this.

First holy should have a Regen (Divine Benison weaved) on the tank in the stun GCD to stabilize them, followed by 2 more Holies. Then if Cure 2 spam is needed, so be it, you provided 7 seconds of immunity.
