I've seen my fair share of topics complaining about the recent changes to Demon Hunters, and how we're nerfed, our class is broken, and how we're useless now, and whatnot. To respond to this, I feel some general knowledge may be needed.
First off, there is a difference between being 'nerfed', and being -balanced-. Nether Tentacles was a huge problem and was definitely very overpowered, especially for a mere ten hatred. It could hit multiple times, and dealt massive damage. That's a game-breaking skill. Now that it's been changed, I hear Demon Hunters complaining non-stop that we have no useful offensive skills anymore, and blah blah blah. This just isn't true.
Multishot does more damage, to a wider range of enemy units, even if it can't hit three times. Impale (especially with the Grievous Wounds rune) is capable of doing Three Hundred and Fifty Percent weapon damage, and that's not taking into account crit damage bonuses. That's one of the best (if not -the- best) single target damage abilities in the game. Smoke screen doesn't last three seconds so you can't just stand there and AOE everything down with no worries about taking damage, ever? Whatever shall we do now that we have to actually engage our enemies at range and use defensive abilities.
Now lets look at some statistics. I believe I read recently that Demon Hunters are the most played class, still, by a vast margin. Why would this be? Because it's still -very- easy to progress as a Demon Hunter compared to other classes. We do more damage than other classes, from range, with low-cost defensive skills that make us not only take less damage, but mitigate it all together. Sure we can't run around with 5k HP and 250k DPS anymore, but it's not like we're a ruined class.
Take a look at the Witch Doctor for example. This is a class that through nerfs that were necessary to balance other classes (I.E. Attack Speed and Demon Hunters, again), has been severely hurt. Now there's only a small handful of 'viable' builds that I've seen work from some of the best geared Witch Doctors out there. And believe me, most of them have tried harder to find good builds than most of the Demon Hunters out there because there are still staple skills that our class 'needs' to succeed. As it stands, the only build that I've seen that really works well in act 3-4 from a Witch Doctor is the mass block and life leech rain of toads build, and even then they can't do any realistic damage. So killing things takes ages, whereas Demon Hunters just Multishot a room and with Sharpshooter, and crit everything to dead instantly. Another thing to note, is that even with the 'tank-Doctor' build, they can only deal with so many mobs at once, while Demon Hunters can kite a seemingly endless number of enemies with decent play and just a little bit of scoot-and-shooting.
In conclusion, I guess what I'm trying to say is Demon Hunters... Your options are there. Spend less time raging at Blizzard for balancing our class, and spend more time figuring out how to abuse (in my opinion) the other abilities that give Demon Hunters a step ahead of the other classes. Believe me, there are plenty there that still make Inferno a cakewalk.
