Caltrops working effectively would bring back the kiting ranged DH. You introduced this thing called Monster Power system and rendered all our skills useless, the least thing that could have been done is to re-scale the only way we could zone ourselfs against monsters, Caltrops. Caltrops working properly is step 1 to improving zoning with a DH.
You know, caltrops isn't the only thing. There are few other things that easily be changed to make DH gameplay very exciting at the higher level, eg how things like Sentries could be an excellent way to make multi-dpsing action possible and effective on the DH at all levels. But I do not even have the will to go into it, when there is such lack of communication and somewhat ignorance on the real issues, which many many experienced demon hunters would like help on, to make their gameplay exciting and worthwhile.
I have listened carefully to the Devs insights on Archonthewizard's stream, and frankly was very disappointed by the lack of care and dis-interest into the class. Instead, if you do not mind saying so, I got the impression that the devs were a little arrogant about it that they think they already know everything, and that it's totally fine, and plus, that DH is supposed to be a subpar class. Even the solutions being talked about did not impress me at all because talks about buffing the damage of this or that, cutting the hatred costs etc, these are in my view not really how you are going to solve anything at all for the DHs.
I just want to ask, what are you doing? What is actually gonna be done before the expansion? Who from the Blizzard team really truly understands the demon hunter class and works on it? Can we talk with them to read into their thoughts? I am sure many DHs would have a zillion questions they would like to ask.
I have been part of a DH community which loves the class for its uniquess and its gameplay since day 1. I am sad to note that I am one of the very very very few that still consider myself as a DH player, although I started playing some CM Wizard lately.
This is just my 2 cents, as I just pass by the forums. :)
