I took a break just as the first raid opened up, come back a week ago, im now 854 on my Dest Warlock (Main) started to farm WQ's for upgrades / and get my Artifact traits unlocked etc, not sure what level my AK is at the moment, its fairly low i think? i havent unlocked all the class hall stuff either, and Nightfall Faction is still honored.
I feel there is so much to do its hard to decide what to focus on first, i have done the Karazahn attunement stuff now though, but not stepped foot inside, right now im basically running Mythic/Mythic+ when i get an invite in guild, and just farming up WQ's and finishing off Suramar quests and other quests in my log.
Im enjoying it though, the guild im in has killed most of the raid bosses on normal, slowly working towards Mythic raiding. Warlock seems to be in a better place for dps now, although my burst is really really nice, my sustained does not seem to be as good.
Its still a lot of fun though.
