Stat Priorities
Stat Ranking
Intellect >>> Crit > Haste/ Mastery >>> Versatility
Stat Outline
Intellect is a flat damage increase to all your abilities.
As for secondary stats, it comes down to damage per point. Here is an outline of what the stats do and how they interact with Demonology’s toolkit.
Haste: Increases casting/attack speed for both you and your pets. This is especially relevant for imps as they have a set amount of firebolts (6) and will time out faster with more haste. To offset this, you summon imps faster with more haste so it evens itself out in terms of rotational gameplay.
Mastery: Mastery increases the damage from all your pets, as well as implosion.
Versatility: Gives damage to all your pets and abilities, and half of that damage bonus as damage reduction. In some situations you can choose to use a higher versatility gear setup to survive certain mechanics, although I doubt with the current state of warlock defensives that will be an issue outside of PvP.
Critical Strike: Crit gives all your abilities a chance to deal double damage. This can be further increased via Demonic Brutality and has some synergy with Improved Demonic Tactics (although this talent is currently not played).

Orc is the best Race for Demonology Warlock.
However, the difference between the best and the worst race is 2% so if you prefer to play another race you should play that instead.
