Grizzle gave you the correct answer for S1 above (the act of entering Eclipse (more often) in S1 was more important than being in the right Eclipse, due to the S1 4pc and other proc talents), but as of the May 9 changes, this is no longer the case.
These changes scream as loudly as possible “use Solar Eclipse”, and it is pretty much a sad overcorrection. The sims at the bottom of the Dreamgrove Balance page have been updated for these changes here:
Solar is so strong as of this upcoming Tuesday that you’ll actually do Solar+Wrath until there are more than three targets, I believe (that was the case as of last night).
I wrote this a little while ago:
I guess we “got our wish”. Instead of doing the actually-kind-of-fun degenerate gameplay of always just entering Lunar super quick no matter what, we’re now going to do the kinda-unfun degenerate gameplay of Solar+Wrath on a 3-pull.
So yeah, we use Solar now, as of Tuesday (May 9), almost too much. Enjoy!
