I like the idea of having a base build for yourself, instead of just an endgame build.
Here's an idea, offers Crowd Control in Slows, Stuns, damage in Fire, Physical and Frost, as well as Healing.http://us.battle.net/d3/en/calculator/demon-hunter#fVbdgP!cTf!aZc.Yb

AoE build where the point is to be 10yards or less from enemies at all times.
Obsidian Shadow Power gives you dodge chance, Alabaster Chakram surrounds yourself with spinning Charkrams, Indigo Multishot allows for a pulse on yourself that damages nearby enemies, Crimson Marked for Death damages nearby targets if you hit the Marked target(easy with RoF/Multishot), Golden Grenades gives 7 hatred per shot(9 with Grenadier? do they stack?), regular Rain of Vengeance.
With the 40 second duration of Chakram, and 30second cooldown of RoV, Multishot will cost 15 hatred, so it's not a SUPER hatred-intense build, though Golden Grenades with Grenadier will keep you topped up easily and Hot Pursuit will get you from one fight to the next quicker. Vengeance will help to fill up your hatred pool quicker when you pick up health globes aswell as increase the max, allowing for max Multishot spammage when you need it.
Does the second build even need Grenadier? Hmm... seems almost a waste of a passive for +2 hatred generation. Maybe take Brooding instead of Grenadier?
