What would you do first on Dawntrail?

[Iscah]

Fully expecting the solo instances to not work due to congestion, so we are going to FISH, baby.

It hasn't been an issue for the past two expansions, so why are you "fully expecting" it this time?

[Jojoya]

Avoiding log-in congestion by doing MSQ on my main while hanging out with the Marilith FC that I have alts in. Going to stock up on Squadron battle manuals in advance since I won't have access to my FC's buffs cross data center.

I would marry Wuk Lamath and live happily ever and after ♥

[SkyCake]

Hrothgal first.

[TheMightyMollusk]

I'm expecting another DDOS attack on launch, because people are jerks.

In what is essentially tradition for me at this point (been doing it since HW), I will be leveling one of the new jobs (likely pictomancer) and then take it through the MSQ. Reason for this is that, to be quite honest, the changes made to already-existing jobs, be it addition of new skills or revamp of X or Y system... is never truly enough to make the job feel "fresh" to me, and that feeling of "something new/fresh" is something I look for in new expansions.

I'll be spending all of my time in the character creator making a bunch of Hrothgals till I find the look I like probably won't see the MSQ for days haha.

I can save you from that. Use the Benchmark when it becomes available. It will have the Hrothgal CC available and you can use it to your hearths content. Then save your perfect gal and load it in the game when DT comes (that is if you play on PC, if you are on console, then just take a picture of the CC options from the benchmark and recreate your gal in the game's CC), you can also chug a fantasia before logging off for the pre-expansion maintenance and when entering back in the game you can change the appearance directly (this will save you from being in the Que twice).

I've got a whole itinerary planned out. First in the lead up, I'm replaying 6.0's story to get a good grasp of just how long it will take with my current schedule. If it takes a week or more, I'll maybe take some paid time off of work (It's use it or lose it where I work, so this is as good a time as any)
I'm still trying to decide on my new main for next expansion. It's either going to be Scholar like I've been since I started Heavensward's story, or Black Mage which I started ARR as.
Once we're finally in the game, I'll make a point of keeping my gatherers leveled along with my combat job just to minimize backtracking. The crafters I choose to level first will be the ones that can make my crafted gear set once we know what goes into making it.
Plan A for week 1 gearing is to craft my own set before the end of savage week 1, but Plan B if I don't make it in time is to get to endgame week 1, and do normal raids. For both of these, I'll prioritize Left side gear so I can focus on the Extreme Trial for the Right side gear when I don't have any timed gathering nodes to go for. Then there's Materia. Any time not doing anything else, but especially when I've already got the crafted gear, I'll be spamming the endgame dungeon for materia drops.
Then and only then, after I've got a melded set (not pentamelded, but just single overmeld probably), and I'm ready to jump into Savage will I take a break to go level my new DPS main, Viper.

Endwalker was my first expansion, and I started in earnest the week it launched. so I've been behind the entire time. I only just last week beat P8S for the first time (got the mount, haha!), and I'm starting to prog through P9S. I finished 6.0's story just a month before 6.2 dropped, and wasn't able to beat P4S when it was current because of it. That changes here. I'm going to get best in slot for a current raid patch, I'm going to make a billion gil selling other gear sets to people. It's going to be a great time!

I believe the first thing I will do is use my free Fantasia to play with the new updates next I’ll redo my glamorous with the new second dye channel then hopefully try out some of the new hairstyles from the contest once my glam is set off to the new world
