Ixal's exp for crafting level for expansions

I knew Ixals came first expansion and 50lvl crafting.

But, I wonder... If my character soon get 50lvl Disciples of the Hand.
When Ixal's exp not long for 50lvl+? (60lvl heavensward)

It stops being worth it as soon as you hit level 50. After that you should use the Moogle dailies to level.

You can't beat the exp from moogle dailies, but you still might find some value in Ixal if you are after moonstones or materia IVs.
