If I were to put my money on an Herbalism passive, it would be something about increased health regeneration.

Yes, because everyone of the same class wearing all the same equipment because there is no variety at the top end doesn't....

Agreed. I don't think that necessarily EVERYONE will go for the profession that provides the best buff for their class, but I think a lot of people will, and eventually playing a rogue herbalist (assuming herbalism doesn't do anything great for rogues) will be like playing a female dwarf.

Every class can benefit from increased Mining. I also seem to remember something about critical strike rating applying to both spell and physical hits, so the Skinning ability would be useful for any class that tries to damage stuff. . . like every class when it solos.

What? Most classes already are, because the items they produce are most useful for certain classes (Priests wearing plate armor?).

My Rogue is skinner/miner. Even more OP!

That's not going to happen... if everyone went mining, the market would be flooded with ore, the price would drop and mining would no longer be an economically feasible profession.

Tauren get a 5% stam racial, but not every horde warrior rolls Tauren

Heh, that's called "natural selection"-- if the PUG demands that, they'll probably either ninja or wipe 500 times.

I'm not sure why the wouldn't. I mean you can already to the self only enchants, and make the self only jewels. This won't shoehorn anyone more than they already are (priest + tailoring comes to mind). The buff is nice, but not totally outstanding.

As an assassination rogue who will be even more crit based than I already am come the release of the expansion, I'm quite happy I didn't drop skinning. And skinning has always been intended to couple with leather working, so this is essentially a buff oriented towards classes that can wear leather - druids and rogues.

I'm going to guess if herbalism gets anything, it'll probably be something sort of lame like +10 all resistances.

Ditto.

After spending 100s of gold for that last +3 stam when min/maxing, +35 stam for something I have already is orgasmic.
