Eclipse is the central point of our damage. The better use we have of eclipse, the more damage we do. High movement fights or dry periods without eclipse will hurt your DPS. As your haste and crit increases, so does the uptime of eclipse, and you will usually find that eclipse procs rather quickly after the previous one ended. The best way to keep your rotation smooth and get the most out of your eclipse is by applying a bit of clairvoyance – and a bit of luck.
The most common way to handle going from one eclipse to the next is by landing one spell outside of eclipse, and immediately follow up with the next dot you are going to use. The one second you spend on casting the dot gives you time to see if eclipse procced. For example, if you are casting starfire during a lunar eclipse, make sure one starfire lands after eclipse has ended, cast an Insect Swarm and see if solar eclipse procced. If it did, you can start casting wrath immediately, and if it didn’t, well, too bad. If you did not do this, you would continue to cast starfire, notice solar eclipse proccing, follow up with an insect swarm and then begin casting wrath. You can save a few more seconds on eclipse by seeing if eclipse might proc on the first cast after the previous eclipse.
Likewise, as you are coming out of solar eclipse, cast one or two more wraths and follow up with a moonfire. Because of the travel time on wrath, it doesn’t hurt to do more than one, and then use the moonfire to see if eclipse procced.
Should eclipse proc in the middle of a cast, don’t stop casting. Just follow through and alter your rotation accordingly. You don’t want to stop a spell cast halfway through.
