Is it true?

I think players should be allowed to reach max level on all crafts but I also think there should be a limiter somewhere. An idea would be 'specialization' in which the player chooses one or two specific crafts to specialize in, allowing the player to not only craft items that would be impossible without the specialization but also an easier time crafting items under said specialization in general. Players would then be able to freely switch specializations, but at a steep cost (guild marks might be good since max level crafters will have all the guild-items anyway, but also prevents the player from switching too often).

This idea could be taken further to include special Guild Tasks (the things you get from the Task Board) that would only be available to the player's specialized craft that would reward tokens that could then be used to buy unique and untradable equipment with the added effect of a much needed gil sink.
