First for reference, the patch notes where all the changes were announced:
I've started a thread for ongoing versions of WrathCalcs as I keep refining the model based on the new rotation:
Finally, rather that restate all the basics so far, here are some posts with the analysis I've done so far:
Overall I'm happy with the rotation, but am still trying to keep thinking about things that have to be iterated. I'm sure more will become apparent as we have an alpha to play, but they've given us such nice and detailed notes that we can get pretty far already.
Some various points for potential discussion:
--As discussed in the second of those blog posts, a significant change is cutting a rotational spell by merging Moonfire and Sunfire into one button. The upside of this is clear; it will great freeing up a core button. And it generally makes sense since the goal will be to only use each DoT when it's getting a nice Eclipse buff. However, we should think through the ramifications of, for example, not being able to multidot with both dots, or not being able to apply both to a fresh target.
--Astral Communion has the potential to be very interesting, but rather complicated. I'll try to get around to posting some math I did on it, but it's summarized in the blog post. No rotational DPS benefit (good), but can be used to set up a high damage burst in a short fixed window when you need. I think the timing needed to judge when to start AC to get Eclipse where you want it at a certain moment (which is itself non-obvious) will take a lot of practice.
--Right now, AC cannot be used out of combat, and we can't set our Eclipse anywhere but the center for starting. My proposal would be to mirror the current behavior: Eclipse remains still (wherever it is) anytime you're out of combat, but you can use AC to move it even then. I welcome any thoughts on whether this would have any issues.
--As discussed in the blog post, Sunfire timing is weird and nonintuitive due to snapshot mechanics and Pandemic. Personally I'd like to keep the Eclipse DoT snapshotting, but so far I haven't come up with a way make Sunfire natural the way that Moonfire is.
There will be specific numbers/modeling issues too. I got into some of them in WC thread, and I think a lot of interested people might get some info just by looking at WC itself. Once we have an alpha to play (and in particular, reasonably final spell coefficients), there might be a lot more of the usual talk about optimizing numbers.
One specific point on planning out optimal play: with the current (likely placeholder) spell coefficients and revealed passives/perks, the DD component of Moonfire is too high. It actually beats out Wrath in DPET. I've of course ignored this (and not made rotations that just spam Moonfire as filler), but it does make it hard to answer certain questions of optimal DoT usage. When there's no actual downside to refreshing as often as you want, questions of how best to use DoTs during say movement, multi-target, or procs don't work well.
