I currently am setup as follows:

Pally - Eng/BS
Shaman - LWX4, Ench, Alch, JC, Inscription

However, WoWHead currently states there are 228 BoE crafted by profession items requiring between level 71 and 80 whereas there are only 17 BoP items. If that doesn't change, I will change my professions, particularly LWX4. In TBC, LW could give you a very good head start at 70 in terms of gear but it doesn't appear that is still going to be the case at 80 so there is no reason to hold on to that profession.

It seems, the developers are putting the incentive in the little extras instead of the gear. If you check the WoW forums there are many many posts on this subject. In fact, the developers have stated that they don't want people to feel forced in to a profession to gear a particular item like the BS weapons of TBC. They want people to do professions they find fun.

With that said, I'd try to pick up mining, herbalism and skinning if things don't change. Maybe tailoring to get rid of all this cloth.
