I brought my DPS up to 10k, and thought wow that's kinda low, i hear most people in Inferno have 20k+ so i was thinking what's up with that?
Then i watched a live stream and saw someone was hitting 22k damage and was like wondering how the hell they were doing it. I ask what there passives are and they open there menu and show me. Passives made the difference between 10k damage and 25k damage.
READ THIS PART IF YOU ONLY READ ONE THING:
Make sure your passives are:
You will make your DPS way higher. I also found that using Bola Shot > Thunder Ball as your left click as it will stun often and do good damage, and using Cluster Arrow > Cluster Bomb as your right click is a very good setup for bosses and elites. *Especially in Inferno*
Also you can use Elemental Arrow > Ball Lighting is a good AoE and damage because it can often hit the enemy more then once. In open area's especially parts of Act 3 Chakram > Twin Chakrams can be extremely effective because they can hit up to 4 times if your enemy is moving the right direction and **can also be used between height planes** (If your standing on stairs or above a target or group you can cast them in that direction and they will travel through the empty space and down to there level, you can hit them and they can't hit you).
Another thing you can do to help boost DPS greatly is use Caltrops > Bait the Trap and use the ability often and stand on the rings created, this will make you Crit 10% more often.
I personally use Smoke Screen > Lingering Fog and Vault > Tumble because enjoy the speed and being immune to damage, you can also swap out Caltrops for Preparation > Backup Plan when your in need to be immune for longer periods of time or are wanting to travel to area's fast. I only recommend doing this in low difficulty modes before the end of Hell and Inferno or in area's were you don't require the higher DPS.
The last skill i normally use is Rain of Vengeance > Dark Cloud because of it's high damage and the especially because it moves with you and lasts a long duration of time. It often help's soften up large groups of mobs so that your main AoE can finish them easily and quickly, as well in boss battles it can allow you to do some damage even while you are having to kite. Standing in a Caltrops ring that has the Bait the Trap rune will make you crit very often and you should keep this in mind when high DPS is a priority. In my speed build i use Rain of Vengeance > Stampede and swap the rune out because the knock-back can help greatly when trying to run by groups of enemy's that would normally stop you while using Smoke Screen.

This is the first time I've ever written anything like this so i hope this is helpful and worded in a way that is easy to understand. If you feel this is helpful and you've gotten something out of it please bump this thread so that others who are also having issues getting there DPS can help get out there and kill some demons! **especially elites in Inferno**
