It may be a little bit op, but it added a high skill cap to aff/demo. Warlocks might not suck in WOD, but the definitely wont be as fun to play. Quality is really shitting (i fixed it) but I am sustaining 1.6 mil+ dps near the end with 1 real application of dots + haunt/MG weaving when appropriate for a bit over a minute. aside from shitty hero drums/food/flask this is self buffed.
