One of the things I looked forward to most in Cataclysm was the remove of Specialization training for my Professions. I specifically skipped choosing Armorsmith or Weaponsmith on my Death Knight because I knew it wasn’t going to matter for very long (though it did in turn make for a long or expensive climb through skill points). Now, I have access to all Blacksmithing recipes. Same goes for Tailoring and Leatherworking. Not for Engineering.
Engineering is already a misunderstood profession. For starters, it’s a tonne of fun. My Shaman went Goblin, and it’s been a hoot. But, fun factor aside, people don’t take Engineering because they think it’s expensive and that it yields little in return because most of the stuff you make you have to be an Engineer to use. Whether that’s entirely true or not is for another day, because only having access to half the recipes for the profession doesn’t help entice players.
Now, Engineers aren’t the only ones who were left out in the cold on this decision. Alchemists also must still choose between Potion Master and Transmute Master. So while the gear making Tailors, Blacksmiths, and Leatherworkers can make whatever they want for whomever they want, Engineers and Alchemists are still stuck with one path or the other (or subsequently paying to switch).
I’ve found no explanation for why this is. To be honest, I doubt I’d find one that satisfies me either. It should be all or nothing. Then again, weren’t orange recipes supposed to grant three points instead of one? Why are my Scribes the only ones who have this happen?
