Quick 3 star question

Are the three star recipes (or the master book 4 recipes) only craftable by those who have the specialist in that class? I just noticed the 3 star recipes for my specialists show up fine and the ones for my other classes are greyed out. Just curious. Still gearing so I haven't gotten to the 3 star stuff yet.

Short answer: yepp!

All current 3 stars are specialist locked but seeing 3.3 is coming it will most likely be removed with that and all new recipes again will be spec only >.>
