hi, noob question, im doing afflock with soul harvester build. Crit sims realy high, almoust as int for me…so im stacking crit. (spam bolts and free MR from nighfall crits). I know im probably totaly doing it wrong as most builds seem to be haste. i know my fear will take longer, and that my shard generation is bad. But, crit sims 50% higher then haste. Am i totaly wrong?
Cough cough cough…
As a warlock, there should be no room of doubt in your heart 
.Haste will always be your friend as a warlock: as soon you are able to cast fears, shadowburns, chaos bolts etc, the better. Maybe in mythic dungeons or raids, it is better this expansion using crit ( personally I haven’t t tried yet) but playing PvP, haste is the best. Your dots will burn faster, your Malefic Raptures will scare your enemies and make them use everything they have to stop you. Basically warlocks have a very high fear factor
My humble advice to you is… Warlock is a difficult class, it requires a lot of patience and steel nerves. Play whatever class makes you feel good and comfortable. Whichever class is closer to your ego, like I do. I wouldn’t change warlock for nothing, even if it’s bottom DPS ( hopefully that will never happen)
Hope this is helpful my little padawan
