I'd stick to starfire spam as well as the 4p t7 bonus (if the rest of your gear compensates for lower mana pool), wrath under a solar eclipse with t8 2p bonus isn't worth it if you consider the time spent clipping wraths could be an extra 1 or 2 starfires in a shadow crash.

FoN is worth about ~30k untalented on this fight so it's still worthwhile.
Probably want to stick iFF on it as well.

Wouldn't it be more worthwhile to have a warlock keeping CoE up seeing as it lasts 5 minutes if you don't have an unholy DK? Does E&M overwrite CoE?

Best case scenario, yes but when you can't ensure a debuff uptime on a target, better for raid dps.
Anyway, sidetracking!

Last week we tried vezax hardmode for the first time, i went for a starfire spam first couple of tries, and found myself in a big mana troubles, althought i was top damage done. I spammed starfire for an interest non stop in shadow crashes, and was on 127 mana when add spawned.

If i do think right then you should be around 35-40% mana when add spawns to put out maximum dps on him (starfire spam ignoring eclipse). It is all about finishing add asap, as melee should be able to finish off vezax after.

For Vezax before Animus im going with wrath spam, and starfire to proc eclipse only, ignoring dots but using iFF and FoN, althought keeping an eye for mana and stopping if things look bad, as add dps is most important, it is an insta wipe if you dont have enough .

Tested this out, E&M doesn't overwrite CoE. But as far as keeping the debuff up if you're having mana issues you can probably get by just hitting a starfire every so often to maintain uptime rather than having locks miss out on dps. Especially since after a few attempts you can probably gauge how your mana will look after the Animus spawns/dies.

It should buff lunar eclipse. Bet they didnt want to fix the *bug* because they want both eclipses to be about the same dps, but they cant find a way to do it.

GC explicitly stated that they did not want to "fix" the "bug" because it would introduce complicated code to the Starfire spell that would only be useful for a few months, but would have to be maintained for the life of the game.

So with the upcoming fix for the 4 piece T8, is stacking haste the way to go?

I don't foresee Haste becoming noticeably less valuable when 4T8 is live. Given that the proc will only be happening once every 25-30 seconds, there doesn't seem to be much basis for your assertion that it will have some large effect.

The obvious answer to this is to make this ability a talent in the next expansion, like they already have done with some previous set bonuses.

... like we don't have enough procs to watch.

I still think not refreshing IS in the last 5-6 seconds of Eclipse is still a valid view, perhaps this could be different if you're doing a Solar Eclipse rotation.

I am curious to see some of your guys UI's and perhaps any specific addons you might use to track Eclipse, DoT's or just basic look and functionality. I'm kind of leary to start a UI thread since I have only really been super active on these boards since WotLK, prior to that I just read the Resto threads. It's an odd request since I am pretty sure the majority of us use Squawk and Awe and I thank Adorielle for that but I find i'm still curious.
