Is this acceptable behaviors for a Tank?

Just a garbage tank is all. No worries.

I'm gonna have to agree here. A good tank doesn't run off without basic mitigation, and doing a pull that big in DF should be run by your healer first to see if they're comfortable with it. At the very least, check their gear while you wait for Protect and Stoneskin.

Running off like an idiot again after the initial failure just compounds it. If I wipe on that pull, I split it in half for the next attempt.

The fact that she had to pop Hallowed that soon into the run should have been a flag to THEM that something was up, or that they were taking ridiculous amounts of damage from something (ie: Should have checked their debuffs, positioning, etc...)

I always pop Hallowed Ground on that pull when I get it clear to the first boss. Same with the first pull in Brayflox. It gives the healer a few seconds worth of free space. A WHM can absolutely tear those pulls apart with Holy, but a lot of them won't do it unless I throw HG up because it's a lot of incoming damage and Holy is a slow cast, so it's several seconds for the initial stun to go off.

Oh, of course you want to use HG, but they used it as a save, not in sequence from the sounds of it. Of course, that's just my take on it.
