Arcanic Pulsar: Increases the damage of your starsurge and after 9 starsurges gives you celestial alignment/incarnation for 6 seconds (as well as astral power every time it procs). This one is by far the best option for balance druid but it loses most of its value after getting one.
The general rule is: get 1x arcanic pulsar and then go for the ones I will list below.
Streaking Stars: It’s the best single target trait and it heavily increases our single target burst potential (which makes it very good for raiding). This trait is pretty straightforward, for every ability that you cast that isn’t repeated during your celestial alignment window, it deals “X” amount of damage. When you have celestial alignment activated, make sure to not repeat the same spell to make the full use of it. It deals damage on spell impact, so keep that in mind if you want to min max your damage to the fullest when your celestial alignment is about to expire.
Treacherous Covenant: Super solid option in both M+ and raids, its in my opinion the third best option you can get. It has its downsides but the amount of DPS it gives you makes up for it.
Power of the Moon: Solid for sustained multi target, pretty much completely useless on single target. Don’t get more than one of these if you decide to use it on sustained multi target.
Lively Spirit: Innervate is a very valuable tool for healers in a raid environment and this is normally a trait that you might not want to get. However, in case you don't have the options above, it can be good for your DPS, especially in burst situations (if well coordinated with a healer). This is a very good pick in M+ if you, your healer and tank work around having you burst big packs with the innervate buff and normal moonkin cooldowns.
Other traits aren’t really worth mentioning as they will pretty much not have any place anywhere.

Arcanic Pulsar: This talent doesn’t really change anything in our gameplay, with the exception of situations where you want to save your “proc” for a burst window phase.
Recommended Azerite traits
In pretty much every scenario you want to use the following traits:
Yes, even in M+. The fact our AoE is one of the weakest in the game and there’s basically no trait that makes it good, you’ll always wanna go for single target / 2 target options.
