Achievement hunting?

[Zarabeth]

Hunts, crafting, beast tribes, gathering/fishing, I hate them but fates, Gold Saucer, gardening, pvp, ponies, birds, and so on... There is so much to do I don't think I could ever get all the stuff I want to do done.

Not sure how much you've raided in the past but maybe there are some Alex Savage or primal mounts you've missed.
Beast tribes, new and old.
Relics or Anima weapons.
Mentor mount.
All 6 tank mounts.
Sightseeing log.
Achievements for leveling all classes and jobs. (Combine with desynth leveling.) (Do chocobo and fate challenge log together.)
Gold Saucer mounts.
The Hunt and related achievements.
Treasure maps.
PotD achievements if you don't have them.

Some of these are not level 70 but may still be fun to do on the side.

I should warn you, if you ever feel the temptation to hit the crafting luminary achievements from ARR then it's going to take a literal fuckton of shards and mats to do it all. Like, I finally started doing them myself recently, and it's going to take me another 12k wind shards just to spam Rosewood Lumber enough to finish the Carpenter luminary. @_@

Those are slightly easier(though still a pain) to get than the gathering ones. Especially come 4.2 with the 999 stack size, and being able to auto-synth some of the items. I'm holding off on those until we get 4.2 and those stack sizes...then I just need to gather for a month straight, 24 hours a day, to get those achievements...will probably take me a few years with how much I gather

Some achievement tracking sites. They don't track all characters, just those which were name searched once and if they have public achievements unlocked on lodestone.

It doesn't include Legacy achievements, only those which are still obtainable (except every seasonal event).
Also, if you enter achievemnt name in search, it'll show it's relative rarity with % of registered players who got it.

Main JP tracker, it has two colums.
First is number of earned achevements, second is total but this time it inludes Legacy.
Pink name = legacy player, blue = non legacy, crown = was a leader at some point, star = was in Top 10 at some point.
To add you name you need to enter it and your server in 4th menu on top.

It excludes Legacy and seasonal achievements or mogshop/merchandise minions, so tracks only anything that can still be obtainable, but it severely lacks player data.
