Thornmarch Hard Mode critical bug, SE thinks there's insufficient information.

HAVE to is a strong word :P Back in 2.1 Ive had groups kill them in just about every different order. We just mostly agreed the most annoying ones were BLM, WHM, and BRD. So we liked killing them, to make the fight less annoying.
(On a side note, we once had the boss wipe us, cuz the main tank of PLD, was in sword oath, and his damage in sword oath was enough to enrage the boss in the 2nd phase each time. It wasnt until the 4th wipe, someone checked the dps, and saw not a single person attacked the boss, other than the PLD lol)

Any kill order is fine, as long as you don't kill the two tanks before the other moogles IIRC. I remember someone telling me that if the WAR or PLD is killed and other moogles are up, he will immediately do the "I KEEL YOU NOW" thing on his next Memento.

But I've gotten through Thornmarch several times, in fact I did one just a week ago and it was fine. Because, you know, we killed all the adds.

Go figure. Do the battle correctly, win.
Screw it up and die.

The way it should be.

EDIT: Was watching the video.... the guy recording who dies only has 3,800HP which is barely over half what everybody else has. Like, seriously, he put no effort into even getting any Ironworks gear, which is buyable the moment you ding 50 (and there's a good bit of MSQ between Praetorium and Thornmarch, easily enough time to get some Ironworks gear). Heck the Praetorium run you go through the first time should be enough to buy at least 1 piece, and then the roulette would give you enough to get 2-3 more, and that's just the first day you ding 50. Not to mention adding Trials roulette to that, too. Also, they could buy some Lv50 craftables, too.

Definitely a player problem. Maybe they should just simply raise the I-level required to 100 or something.

Also, shame on the OP for not casting Succor/Adloquium. He even talks about how he's about to do this big attack and......he doesn't bubble anybody. While playing the healer whose job is all about bubbles. An adlo would have saved his life. Heck, Succor would have even done the same. He took 3854 damage and he had 3814 health.

Issue is still unresolved as of the latest hotfix patch as I took 3.4K damage from a transition Memento Moogle that was weakened by Reprisal and Addle.

It's still causing more damage then all of the EX primals do with their phase transitions (Shiva EX is the "toughest" primal in ARR, but her Diamond Dust only hits for around 2.8K comparatively) so not very reasonable.

Nobody should have 3.4k health, I mean c'mon. Getting I-level 100+ is easy-peasy even for your first time through. Maybe, before going into your first (Hard) fight, you might want to actually make sure you're dressed for the occasion? Heck, they hand you i90 gear just by finishing your Lv50 job quest. Are you trying to tell me you're going in there without any sort of proper gear?

Not sure why people are acting like you should be able to walk into Thornmarch wearing Lv45 junk that you had on you while you were in your 40s and expect not to die.
