As I've said before, the goal isn't merely to get you to use Starfire and Wrath. The goal is to have a rotation that is more than just 12121212 or even 111222111222. RNG is something we actually want. The best players should be the ones who can pay attention and react to situations, not the ones who can mash their keys the fastest (or download the most recent macros).
The biggest problems with Eclipse are:
1) It's too much of a damage increase. Here we see the problem with overbudgeted talents. The RNG wouldn't be an issue if the magnitude of those random rolls wasn't so huge.
2) It suffers too much from movement. Losing an Eclipse proc when you have to run is a problem, particularly given point 1. Now we have no problem with classes taking a dps hit when they have to move and we don't even mind of some specs pay a heavier penalty than others. But it's a problem when the delta between dps when moving and dps when not moving is so great.
