That ' s a good one . I also made an effort to be the one to introduce myself when I go into a room with people , rather than skulking off in a corner . <| sep |> Lock is an inherently bad mythic class . I ' ve mained lock since cata , they ' re a perfectly good raid class . But lock lacks what makes classes great for mythic . They have long ramp up time as demo , the demo ramp up time is 30 seconds , in 23 minute boss fights you really don ' t have the burst cd ' s as demo is your only good single target spec and yet it is outdone by feral , assassination , fire mage on short fights , shadow priest , and warrior . 5 man dungeon bosses , especially with affixes , involve a fair amount of movement as well , and fight mechanics target the lock more often as you have less ranged to be targeted . Movement sinks demo DPS massively . As demo even with implosion your aoe is utterly mediocre . At mythic 12 packs pulled still consist of 45 mobs . If you want aoe for that , you have two specs to choose from . Both destro and affliction don ' t do spectacularly . Destro because it ' s only great for 2 target fights even fire and brimstone falls short of true 3 target cleave aoe classes . Affliction takes too long to ramp up damage and the trash packs are dead by the time your agony ramps up , and because even then the mobs don ' t die fast enough , your signature sow the seeds aoe is not great . Moreover , if you ' re taking destro or affliction for aoe with their aoe talents , your single target DPS is atrocious . Warlocks work fine in raids because you can swap specs to suit the fight destro for cleave , affliction for aoe , demo for ST . But in mythic keystones for some fucked up reason , alchemy is the only profession that is allowed to work while talents and specs can ' t be swapped . The inability to swap spec or talents is what breaks warlocks in mythic because they simply aren ' t a well rounded class if they can ' t swap talents and spec for the fight .
