Balance druid is one of the specs where stats heavily change based on what gear you’re wearing. So, despite the stats priority above being correct and the “standard” one, I STRONGLY suggest you to sim your own stat weights.
Intellect: is your primary stat. You should look for this stat in all your upgrades.
Crit: increases your chance to critically hit with all spells and abilities. This stat has a big element of randomness, meaning that it may not be as effective as others.
Haste: Increases your casting speed and your astral power generation (as a result you will be able to cast more spells).
Versatility: Increase all your damage and healing done while also decreasing damage taken. Versatility despite often not being the best stat DPS wise, it can have a very big value in progression encounters where damage taken reduction is very impactful.
The best way to calculate stat priorities for your character is to "sim" your characterFind out how to sim
Troll will always be the best damage race due to their racial berserking.
Night elf is overall slightly better for DPS.
None of the new races pulls ahead in case you were wondering.
Generally for enchants, you will need to look at our stat weights. And as I stated before, since our stat weights are individual based on our character’s gear, you want to make sure to see what sims highest for YOURSELF to pick gems and enchants.
When it comes to weapons enchant, the same rule applies. Quick navigation or torrent of elements or Machinist's Brilliance are meant to be the best options, the enchant you should use depends on which sims highest for your character.
