Strongest Job Lorewise?

[EdwinLi]

This, ironically and paradoxically, translates to players as:
"The only way you can play MCH is by first leveling another class to 50, and saving the world by beating the Garleans, several primals, and an Allagan weapon that was tampered with by creatures that want to destroy the planet. But anyone can totally do it, you're just lowering yourself here."

MCH story is dumb.

lowering yourself isn't what the WoL does when he or she becomes a MCH. When the WoL becomes a MCH he or she is the original user of the Machinist Soulstone setting the memories and skills for the successor of that Machinist Job Soulstone.

Currently MCH Soulstone used by the WoL is a clean slate which has no memories to pass on MCH skills. It is up to the WoL to build up those memories so the successor can obtain those talents while other Job Soulstones the WoL has is just the WoL obtaining memories of the Job Soulstone to obtain the power from the past users.

The reason why anyone can become a Machinist is due to originally being a crafter Job where both poor and rich would take on for crafting weapons and airships for Ishgard until the current Guild Master decided to introduce combat for the MCH job. The primary use for MCH, lore wise, is still to serve as crafters mostly for magitek industries such as the Garlond Ironworks, Airship industry, and ishgard's weapon industry.
