Hey there. So I've been leveling up my ARM skill and last night I hit a spot where I'm stuck on the level 45 ARM quest. As of now I have no other crafting skill leveled, and I am very aware that in order to make the HQ items it's asking my only guaranteed way of doing that is by leveing up other crafts to 50.
So my question is how do I get to level 50 if I can't finish the level 45 quest? Do you just skip the main quest and continue doing leves til 50? Do you still get the actions at level 50 once getting there or do you have to do the jobs main quest to unlock them?

Thanks in advance for your help.
