Stat Priorities
Stat Ranking
Early on I would recommend going for the highest item level.
Once you start getting same item level pieces you can start using raidbots to sim for the best piece.
Generally speaking it will be Crit = Vers > Mastery > Haste.
Stat Outline
Critical Strike: Increased chance for attacks and heals to crit. Works well for Brewmaster due to Celestial Fortune which also always works on absorbs.
Haste: Increases energy regeneration, attack speed and reduces the cooldown of Keg Smash, Rushing Jade Wind and Purifying Brew.
Versatility: Increases all your damage and healing done, as well as decreases all damage taken.
Mastery: Mastery: Elusive Brawler grants you a stacking buff that increases your chance to dodge until you have successfully dodged. Mastery also increases your Attack Power.
Races
Just like previous expansions, the difference between races is mostly fairly small, so feel free to play whatever you like the most. If you care about min-maxing then here are my recommendations.
Some races perform slightly better for specific situations.
Dwarf for Stoneform.
Night Elf for Shadowmeld if you want to utilize it for Mythic+ skips.
Earthen for the increased base armor value.
Pandaren Panda can be great if current food buffs x2 outweighs other racials.
