For Starfire under eclipse to out damage an IS cast, I would require 1250 haste rating.
Neither 1750 critical strike rating nor 1250 haste rating are realistic figures at our current level of gear progression, so IS and MF will always be a better use of a GCD than Wrath of Starfire, even during Eclipse.
The one exception is if it's the final Starfire of a Lunar Eclipse, as to maximise on WiseEclipse you'd want to skip out on refreshing any DoTs at that particular time.
The figures I refer to are Damage Per Execution Time as per the second tab of the WrathCalcs DPS spreadsheet.
