Gunbreaker job quest 70

[Marc-Vigar]

Hi

I just got my GNB to lvl 70 and I was doing the pertinent job quest (Steel agains't Steel) to get a new skill, when suddenly I ran into Vitus quo Messalla with like 1 million HP that takes half my HP with a single blow. Everything was OK when the cute Viera NPC was healing me, but once she was taken out of the fight I got destroyed. I didn't fail at any mechanic, I dodged every single AoE and used cooldowns.

I'm currently ilvl 290 and I have 40k HP, I've done all 60-70 dungeons just fine until now and I also did lvl 70 quest with my BLM with the same ilvl without any problem.

Why is this fight so stupidly hard? All videos I found are from people with twice my HP and I don't understand why a fresh 70 can't do a lvl 70 quest like any other job.


EDIT: I somehow managed to beat this guy but I don't think that's the intended way to do it. I ran away ALL the time using defensives and keeping DoTs on him... Took some time but he's dead, though I still think the difficulty is too high and must be reviewed, I got hit once and I went from full HP to 0 both from his AoE and from the stack icon at the start which I am suposed to soak with the other NPC.
