Dancer weapons!

They've done all of the previous primal weapons for expansion jobs.
DRK, MCH, AST, RDM and SAM all have Titan, Ifrit, Garuda, Leviathan, Shiva, Mog, Ravana, Bismarck and Warring Triad weapons.

That's because primal weapons start at lv50 and all of the jobs added so far started at 30 (HW) and 50 (SB) too.

Going by existing precedents regarding crafted and dungeon weapons, HW jobs don't have any weapons below lv30 and SB jobs only have gear lv50 and up.

However the ShB jobs start at 60 so this will be the first time we get jobs that don't encompass the 50-59 level range. We have yet to find out whether they will bother covering weapons below level 60, and there is no guarantee that primal weapons below minimum level will get special treatment.

That's my train of thoughts yeah. They did not make level 20 guns, level 40 rapier, level 35 katanas etc.
They did not add PvP gear for RDM / SAM in older expansions too, right? Like relic weapons.

So that would make Ifrit, Titan, Garuda, Leviathan, Ramuh, Mog and Shiva weapons twice (normal version and shiny version) and the three Coils designs, for two jobs, multiplied by the number of races. (Ignoring the crafter weapons for level 50, like Wootz weapons, Gold saucer models etc.)
I understand that's quite a lot of work. (Given that they should already have to do all the 60 to 70 weapon models too)

The only lowel level weapons skins I can see added is Grand Company gear.

I doubt they would do Grand company gear if they don't they primals. In terms of popularity Grand company gear is a lot lower than primal weapons
