Something need to be done in how tanks acquiring Provoke

[Freyyy]

I thought changing classes was unlocked by lvl 10 class quest.

Isn't it unlocked by the story quest which lets you go visit the other capital cities ? If it's not, it doesn't change anything to what I've said tho since MRD and GLD have different starting cities anyway so you can't look up for GLD skills until that point in the story. Limsa only has MRD, Arcanist and ROG.
