Hear me out on this one guys it just popped into my head and i thought "wow i should post this on MMO!"
So why doesnt blizz make some sort of special items ONLY able to be crafted by someone with a certain combo of professions, like say you have... for example enchanting and tailoring. Then you would have a certain ability available once both hit 525 to be able to craft Enchanted Embersilk or even a certain item that has an enchanted extra stat.
I really will have to think deeper into this but it would create an end game use for some of the crappier professions that arent good for anything but auction house farming.
Maybe Herb and Alch allows you to make special Organic Elixirs that give better stats... or 2 stats or last longer! i dont know but i do think theres alot of potential for something that would work
Lemme know what you all think!
Edit : if this was posted before i apologize i looked back a few pages but didnt see anything similar
