as 871 destro lock with 2 legendaries I actually kind of enjoy playing my destro lock in M+ and raids. I don't really like demo spec due to the micro managing of pets but if forced to play it in a raid for 1 boss I will if I can do good with it. Otherwise I like double chaos bolts flying and being able to survive teeming neltharion pelters thanks to mastery/drain life/ DR cooldown. Sure I'm not top of the meters every pull with 1 million aoe dps and 400k+ sustained single target but I get an easy laid back rotation, with like 500k+ aoe rotation and about 300-330k dps ST in my M+s after burst is over.
It's an ez life.
I wish our chaos bolts hit a little bit harder because when I use havoc and chaos bolt when rng proc is high I might get a 1 million total damage hit for both at the same time. My 862 ret pally hits 950k templar verdict on one mob.. it requires me hitting 2 mobs to match that same damage in one ability .

Actually yes I have my miks scrolling battle text addon to only highlight my crits on right hand side of screen and I always see every chaos bolt that goes off and how hard it is. Sometimes I'll see 500k, 390k, 450k, 600k, 750k, the highest I've seen was around 900k single chaos bolt but that was a rare day indeed..
