Recently posted the following article (warning: some math ahead), but would love to get some feedback:
What are you folks finding to be most useful? Have you actually tried all of the abilities after hitting 60? For myself, the Nephalem Valor buff requires "one build to rule them all", so to speak. Since Nether Tentacles is great for single target and massive AOE damage, the only real hole in the build is for fighting a handful of mobs (3-5). Evasive Fire: Covering Fire seems to fill that niche perfectly.
