I went into Dusk Vigil on my monk over the weekend. We said our customary hellos and started the first pull. As I'm punching, I hear the sound of the limit break bar going up like crazy and I realize the tank is hovering at about 2k hp. "Huh," I think, "is the healer here? Yes, he's here. What's going on-"

Tank dies. We manage to last long enough to kill 2 of the 3 mobs, but ultimately wipe.

We dust ourselves off and I inspect the AST. Oh geez, a level 41 weapon... four of his accessories are int. He barely had 5k health. I hadn't seen gear this behind since the time I got a DRK using the i75 moogle sword in Sohm Al.

It was certainly an interesting run. Any time we fought a pack of 3 or more, the tank's health floated at critical levels and by the end of it, the healer would be OOM. I asked him if he had a better weapon, but he replied that if he did, he would be using it. (Why he didn't buy a lovely i115 white quality weapon from the vendors in Ishgard is another question.)

We couldn't quite deal with the last boss; while the fight is normally quite forgiving, the AST's max hp was so low that virtually any mistake meant his doom, and subsequently ours. We wiped three times due to the AST getting sucked into the whirling gaol and dying in short order - keep in mind no one was new - I advised him to get better gear and we vote kicked him. Our replacement healer not only kept us topped off easily, he spent most of his time in Cleric Stance.

tl;dr For the love of the Twelve, keep your gear up to date D:

Also props to that DRK for awesome cooldown usage.
