You guys LOADED me with some questions, so in the interest of me finishing them by next week, I'm going to try to keep them brief and suggest you read the first post. It will explain a lot of my process without individually saying the same thing over and over again. Instead, I'll be suggesting pieces of gear I would change and why.
Your CC is great, CD is great, AS is great, so good job. Now it comes down to increasing your dex and your weapon. Drop the hellrack for sure and get a manticore. 1200 base damage and 190 dex is pretty reasonable these days. That will add a ton of DPS. Your eHP is too low, so I would suggest improving your life and resists. Consider dropping your andys for a mempo with high dex. Gives you a socket, more AR and a gem slot for extra life.
Your DPS is looking much better, as is your eHP. That looks almost exactly like the sample build! Looking good. At this point, it basically comes down to improving the attributes on each piece. An example of that would be with your bow and boots in particular. You could get a ton of dex on your bow to improve it. The dex on your boots could be increased by 100. You could increase the dex on your bracers by 70, ditch your low AR and get vit instead (kinda like mine). Things like that will be the way for you to progress.
Your eHP is a bit on the low side. You're at a bit under 150k right now. I'd say you want to try to double that if you want to have any sort of tanking abilities. While all your 'direct' upgrades will cost you your left nut, you might need to start considering changing your pieces instead. While it's not ideal for DPS (at lower qualities), a mempo might be a great piece for you. You'll lose a bit of DPS, but you'll still have your attack speed bonus, you'll gain 70+ AR, natural %life and a socket for a vit gem (if you so desire). Also, I think you should change your shoulders. The sample build I've shown has shoulders with 50 less dex and like 25 less AR, but it has 150 more vit. Between the mempo and the shoulders, I bet your eHP will shoot right up.
The reason they can get away with it is because of their ungodly amounts of eHP. They don't even need disc with that! With my disc pool and night stalker, disc is literally never a problem. Going any higher at the cost of DPS doesn't make sense for me, but that's how I play. Yeah, getting to Beast's level is just so far away. I'd rather have the $10k IRL than beast's gear though hahaha.
I'd love to, only problem is I can't see your profile! Either repost here after changing your profile, or post the link so I can check you out ;) I don't know where your gear is now, but 300k without steady aim is seriously high. You're basically talking about 275k unbuffed DPS if that's what you want, and there are only 34 DHs in the server with that… You better believe that 400m won't cover it (unless you're almost there as is). Anyways, post your profile and I'll take a look!
One thing I notice is that your CD is pretty low. That often comes with the burden of the WF, but can often be managed. It basically means that you need to get a soc in your WF. Otherwise you've sacrificed a ton of DPS just for the KB and higher AS of a bow. Your eHP is in a reasonable spot right now, so I'd consider switching out your belt and pants for 2 piece innas. That will add a ton of DPS. That will hurt your eHP a bit, so to recover, get some bracers with some AR, dex, vit and CC on them. You won't need the MS of lacunis with innas pants and will likely increase your DPS and eHP at the same time by switching to new bracers. If you need more eHP after that, stick a vit gem in your helm.
I would be very cautious about dumping huge amounts of gold on single items at your stage. There is still a lot of fundamental things you should do BEFORE you start increasing your per item costs like that. I would highly suggest taking a look at my first post. Every item in that build was 5m (apart from the pants and ring which were 10m each). It seems like that is in your budget and will give you a well rounded build without breaking the bank. Once you get to a point similar to that, THEN it is time to start upping the price to continue improving.
I agree with your comment of a balanced DH. I generally call those hybrids, and that is what all my advice is working under the assumption of. You should know, however, that pure HP isn't equivalent to being balanced. While I don't advocate low HP, there is a point where it gets tough to keep high HP without losing DPS. For that reason, I find a far better measure of survivability to be eHP. It effectively embodies all aspects of damage mitigation into a nice little number.
You've got a pretty nice WF, so that's a good start given that you're dead set on it. Your right ring, boots, ammy and belt are off though. Belt should be innas (great DPS), ammy should have two trifecta stats (CD and CC would be my advice) as well as dex and vit. Ring should again have two trifectas while trying to max out dex as best you can (your CD is pretty useless at 16%, so get something more substantial - again I suggest CC and CD). Your boots should be nats boots. You can get the same stats as ice climbers (less the %life) and will gain the 130 dex set bonus. Shoulders are debatable. I would suggest getting ones with like 150 dex/vit and 50 AR. They are cheap and will help more (could always get better if you can afford it).
You've got a pretty balanced build which I honestly didn't expect by looking at your gear. It's not common to see stats like that using as many rares as you do. You would be much stronger if you were to increase your CD and CC though. You should change your ammy to get both of those. Consider comparing with the first post. I don't really know where to go without changing the rares around significantly. What I find with builds like this is that some pieces where I look to get DPS end up being spots where people have stacked eHP (and vice-versa).
Hand crossbow builds are a tough thing to pull off. You've managed to keep your CD pretty good though, so that's a bonus. Your eHP is in good shape, so it comes down to DPS. Your right ring definitely needs to change, and I feel that innas pants would be a very wise investment. Consider getting nats boots and nats reflection for the 2 piece bonus. If you want to change your armour out, you could go for the 3 piece set bonus of nats. If this starts to hurt your eHP too much, consider getting a mempo. That is an uber eHP booster.
I would probably change out your left ring for nats reflection, but wouldn't jump to getting 4 piece nats. Without a CC helm (which is $$$), it becomes a DPS sink without any eHP gain. You should probably try to replace your right ring with something with higher DPS. If you find that as you're increasing your DPS that you start losing a ton of eHP, just remember that mempos are always there to pick you back up. Those things are amazing for picking up eHP.
