I’m having issues I’m at 375 Ilvl lock and I know the rotation but my dps just continually drops I can barely get it over 7k about a week or so ago I was doing 15 at 360 ilvl . Any tips I’m just confused and can’t figure out the issue
Tbh I’m not sure 
Are you out in the world? Cause of the whole “scaling” system
Look through your armor and make sure you have every piece in the right slot
Try reinstalling your damage meter, there could be a possible update
That’s all I got so far, good luck 
Stats matter at that ilv. I suggest getting some logs together and asking on the Warlock Discord. A google search should bring up the general discord, or ask in the Warlock forums here.
My guess is there is more than one thing going on with your character and it will need some specialized knowledge to fix.
