Crafting question after reading patch notes

[TheUltimate3]

You won't be able to specialize in more than 3 jobs at this time.

I may have not made myself clear, my apoligies.

What I was questioning was, with these six new skills that specialization gives you, you no longer have to level 4 jobs to be good with 1.

Take for example I want to be a weaver, to make anything worth while, I would need to level up cul, crp, and lwr for their cross class abilities. Is this still going to be required?
