I'm not convinced click was taken out for simple dps rotations. We've seen the general analysis go this way:

Methods ranking for MAX DPS:
1) Individual spell management (full micro)
2) click
3) cast sequence

I'm willing to bet the difference between 1 and 2 is greater than the difference between 2 and3. If Blizz wanted to remove faceroll dps then they'd get rid of cast sequence. Click just allowed for a bit more control and custmization. However, to do max content you'd need to micro your rotations. Only after you've gotten the content to manageable or trivial can you really start facerolling.

Watch, we'll see the same posts on these very boards about how the new instances are "impossible". Then, a few months in, they'll all be on farm after gear inflation has normalized.

Take it easy on the /click'ers out there.
