Also, watching the numbers given to the monk's skill in 1.0.7 (especially Wave of Light - which I literally thought was a typo) give me hope that the damage % numbers of us DH will get looked at. Rapid Fire was given a good look, boosted, and now it's pretty much one of the very few skill we have that competes what other classes are playing with, along with Echoing Blast.
Granted, I think that while a few of your suggestions are a bit overpowered, they are mostly quite interresting takes.
The point where I have to agree with you is Hatred Generation. Now, I know most people run with Lyndon, but I'm going with Kormac, just because of that +1 hatred regen. I'm using a rune I thought would be more popular, Entangling Shot - Justice is Served, just for that, so that also, when I'm regenerating my hatred, I can also kite a bit. I'm not expecting to deal any damage whatsoever with that rune, though. I'm also running vengeance. The goal is to keep Rapid Fire up as long as possible. Works pretty well - until you start noticing I'm using 2 actives (ES+Bat), a passive and a dude that gimps me off 3% CC just for my goshdarned ressource. Other classes don't have to go such lengths to keep swinging.
Granted, I can vault in, tank up a big pack, kill it fast with sentries and Rapid Fire, grab the health globes and vault to the next lump, giving me fast farming abilities, but it doesn't feel very DHy to me. I literally play Rapid Fire as a melee ability. Then it dawned on me, I'm playing a very squishy Zeal Pally that only survives because of the snapshotting mechanic. Effective, yes, but I'll admit it does feel wrong. Strafe builds seem to function mostly the same way, with the important distinction that RF is a lot better at defeating elite packs.
I'm also not surprised Gloom is used by almost everyone. Even at 35% it's a lot better than anything else we have defensively. It was OP at 65%. Right now it's not OP, it's just that we're pigeonholed in a way of playing that makes us need to take lots of damage - and it's the best tool for the job we've got.
I hope Blizzard reads your post carefully, assess how far a DH can go and how far a Monk can go given equally powerful gear, and react accordingly in 1.0.9 - even if it's "Itemisation Patch (tm)". Your work desserves to be noticed.
