Movie Summary
There is a myth that demonology warlocks don�t do DPS in high end.
That Demonology is a pure PvP build.
Every time someone recommends a build to BWL or MC in this forum it�s always a MD/Ruin or SM/Ruin build.
After CoS Nerf Ruin lost the % of a 4x bonus damage on a critical, because negative resistances is over in 1.9. You can count only with a 2x bonus from a critical.
You can see only 1 critical in this movie. Only one spell would take advantage of Ruin.
This short movie was recorded in BWL without damage gear equipped. As you can understand this is also a good build for High End.
Have fun..
