As far as the no-generator build, it would be tough to pull off solo, but it works in groups in T1. Health globes are yummy.

No Generator build is extremely easy to play solo. Much easier than playing in a group actually.

The key factors in a DH no-generator build are Reapers Wraps and Blood Vengeance so you can refill your entire Hatred pool with a Health Globe, Pride's Fall for the ~30% cost reduction buff, and the combination of Preparation/Punishment and Night Stalker. Cindercoat's fire cost reduction is an added bonus if you have it for efficiency.

Game flow is to keep your Pride's fall buff up as much as possible and whenever you are running low on hatred use the most efficient recharge available to you (Health Globe, Preparation, Bat). At times you will end up spending most of your Discipline by funneling it into Hatred with Preparation and then you will focus on regenerating your Discipline. This is done either by using a skill that can do lots of AoE hits combined with Night Stalker (I use Twin Chakram) or by using Multishot along with the Discipline regen rune. I find the first option to be most efficient.

You don't need to waste a space on your bar for an attack that does low damage but regenerates Hatred because your primary method of regenerating Hatred is Health Globes and Preperation, and those methods are far more efficient than spamming a weak generator attack. The only thing you need to worry about then is generating Discipline.
