I recently have dropped inscription to pick up engineering. Even with the nerfs, I feel that engineering is still the most fun profession. Now of course for a min/max raid prof you would want to use BS/JC. However people are talking about 71 stat vs a 81 stat or something along those lines. At the end of the day skill will always play a bigger part in your performance over stats. I would keep engineering and enjoy the fun that it brings to world of warcraft.
