This is the only class with 2 resource pool, and we do not gain the same type of resource by spending. We must make an exchange between the 2 resources to gain any amount, but this amount is sometimes too low to cover up what we need.
Barbarian and Wizard gain massive amount of resource per second, with using 1-2 types of resource generator. Barbarian uses
Critical Hits have a chance to generate 15 additional Fury.
Mighty Weapons: 3 Fury per hit
using this build http://us.battle.net/d3/en/calculator/barbarian#.hUR.P!ZY!.ZZY.c
with 50% cc I can gain on average 80-220 Fury per second depending on the weapon choice and the mob density. Using a Mighty Weapon output much more Fury in comparison to an Axe or a Hammer.
Wizard is a bit different, and much harder to build than a Barbarian, you will need items like this one http://us.battle.net/d3/en/item/chantodos-will which have
Critical Hits grant 9–10 Arcane Power (Wizard Only)
http://us.battle.net/d3/en/calculator/wizard#VQYXTh!bWg!YZYccc is one of the more popular builds that can grant the player massive resource. IMO Wizard also have 2 kinds of resource, the 2nd kind if called "cooldown", each other class all have cooldown to reduce the amount of the resource you can spend per second. But a Wizard you can reduce this timer to 0-2 seconds. I can with 60% cc and 2.80 aps, gain 13-19 seconds reduction per second which will also equal to 130-190 Arcane Power if you only have 10 APOC. btw I'm using this build http://us.battle.net/d3/en/calculator/wizard#VQYXTk!fWg!YZcccc
How much Discipline can you gain with your Demon Hunter?
I heard this build will give you a lot of resource http://us.battle.net/d3/en/calculator/demon-hunter#UPYQVh!XUg!ZYcaZZ but I have never tried, so I can't give you a number here. But with this build http://us.battle.net/d3/en/calculator/demon-hunter#ShgYVT!XUT!cZcbZb I can gain about 7-13 Discipline per second. And if we use the 125/25 ratio with Punishment we have 35-65 Hatred per second, but can only be grant every 2-3 seconds. In the first build I see 5 resource generating skills, in the second build I see 3 resource generating skills. For the Barbarian I see 1-2 depending on weapon choice, and for the Wizard I see 2-4 including the weapon as 1. We can always scrap the bat and make it seems like 2-4 but from my experience, I will often run out of resource when I'm attacking. I'm strafing with 2.40 aps, and I do not plan to reduce this number, why would I want to reduce my attacking frequency so I can keep more resource? Where as a Barbarian and/or a Wizard can gain more resource with a higher attacking frequency.
Solution #1 Upgrade Night Stalker
Critical Hits have a chance to restore 2 Discipline.
Discipline is used to fuel your tactical, defensive, and offensive skills
Solution #2 Upgrade Night Bane and Breathe Deep
old post please read http://us.battle.net/d3/en/forum/topic/8796359826
Gain an additional 3 Hatred per attack while Shadow Power is active.
Restore 40% maximum Hatred after activating Smoke Screen.
Solution #3 Upgrade Marked for Death
Increase the area of Marked to 8-12 yard up from a single target. Allow players to multicast, without removing the previous effect from affected enemies.
Same Skill do not stack (as always).
Solution #4 Allow Discipline Attacks to proc Mortal Enemy
I don't believe they work at the moment, and since we gain the most Discipline by spending Hatred. Jagged Spikes, Choking Gas, Trail of Cinders should gain 3 Hatred per enemy per attack.
eDPS scale with your attacking frequency, so the more powerful attacks you can make per second the more damage per second you can make. Even though I have #1-4, but they need to be all included IMO.
========= END OF HATRED X DISCIPLINE =========
so you can stop reading here, I added a bit of extra stuff on the 2nd post
