Hit lvl 19 last night with my HC Witch Doctor. Really enjoying him. Being on HC I'm all about staying alive and trying not to get near any trouble.
Jumping spiders for a while was fantastic for me. You can chuck that jar to the edge of your screen, then the spiders would jump & attack enemies even further. I could attack enemies I didn't even see. Problem with that though is you have to spam it over & over. It's essentially your primary attack.
So currently my build is.

Having the spider queen roam about doing work allows me to be freed up to use my poison dart. I don't think the spider queen is quite as good as jumping spiders but she makes up for it in being self sufficient.
I don't use it that much but feel like I have to have spirit walk locked in loaded. It's my "oh shit" button. Can't risk dying.
Just got Gargantuan. His damage isn't great but significantly better than zombie dogs. Oh well. Just another meat shield which I'm all about. That and he looks sweet.
