Well in the video youre spamming only corruption for all the time, not with full dots up.
Same logic as spriest, spam SW:P on 2 targets only, keep spamming only it, infinite mindblasts, more than 10 in 1 minute
Also boomy too, more dots over targets / targets dotteds, lower proc chance
If u want go by this logic ofc it will seem bugged, if a warlock knows dotting w/o shards and soul swapping to keep high duration , ofc he will use his shards only for haunt.
All locks are fine except funkabizsax wich spams 2 haunts per target + infinite soulburn soulswap on everybody
