Why are there no sources of EXP for crafters below 50?

[Kabooa]

I'd rather see them promote Omni Crafting myself. Consolidated class system on one character is something they promote in every other aspect, yet Omni crafting is a 'bad' thing.The reasoning is all wrong.

The difference is that in every other subsection of the jobs, one job is self sufficient.

you don't need botany to do Miner.

You don't need Gunbreaker to do Warrior. You don't need X to do Y.

Unless you're a crafter. In which case, you need all of them to do any one, because they all bring either a required ability or a contingency ability. This is ignoring the basic ability to also craft everything in the game which significantly increases your profit margin when dealing with multi-component crafts.
