Grinding dungeons for BoP recipes, I’m starting to miss the possibility for having a third Profession slot. This third slot should not work like the two others, because I see the value of limit the amount of professions each character can perform at the same time.
We have two main profession slots for fully utilising two chosen professions. Then a third profession slot should unlock when the main professions have at least 50 skill in each expansion. As example when main professions are Mining and Blacksmithing, one need at least 50/300 skills in Vanilla Mining + 50/300 in vanilla Blacksmithing, and through all the expansions to current 50/150 Shadowlands Mining and 50/100 Shadowlands Blacksmithing.
Now, what would be special about this third Profession slot is that you can only learn one single expansion profession, no more. Meaning you can chose to learn Cataclysm Enchanting, but you won’t be able to learn any enchanting from any other expansions. Also the slot is cleared by daily reset - you simply forget things. All your skills and learned recipes for this profession slot will be cleared, and you will need to learn everything for the given profession anew each day if you want to keep having it.
And in addition to the slot’s temporality, learning any professions for this slot should also not be as cheap as learning the professions for the two main slots. How costly it should be is open for discussion, but I imagine 1 000 gold is appropriate for learning the first skill point. (I don’t remeber whether it starts at 0/x or 1/x skill points.)
