Sorry in advance if this is the wrong forum.
I'm just pondering aloud, but how will the machinist be rationalised do you think from a narrative perspective. Assuming the Machinist isn't "locked" behind leveling a crafting class first (Which seems unlikely, though I may be wrong), the player might not know the first thing about crafting.
Yet from what I gather the machinist doesn't merely "use robots and guns", he tinkers with them, builds them etc. The GSM story arc suggests that GSM is the class traditionally associated with building automata like mammots, since the fine clockwork components are in the domain of jewellery in terms of techniques used. While the plating and rotors seen on some robots are more the domain of armoursmiths. Then of course guns, with their need for high quality, sturdy components are likely to be the domain of BSM or ARM. The ceruleum fuel used is also shown to be very bleeding edge, and is only encountered by crafters in the ixal story arc, even then most the machining is done on specialised equipment rather than with traditional crafts alone.
So how do you think it'll be rationalised that a lvl 50 machinist/level 0 crafter will be able to tinker with highly sophisticated ceruleum fuel systems and automated robots, which the lore already establishes are the domain of experienced crafters?
Will the class be in some way locked behind achieving at least a certain level in a crafting class do you think? (A move I approve of, but undoubtedly would enrage people who just want to shoot guns)
Do you suppose the story stress the player is simply using the tools he is given, not really tinkering with them himself? (Making him less of a machinist, and more an engineer?)
Or will it just be handwaved jarringly, that the player is a master machinist, yet simultaneously incapable of even the most basic workshop crafting
Obviously we won't know the answers til Heavensward comes out but, it's just something that's bugging me and I'm wondering if anyone else has thought about or has answers to I missed.
