Was able to get through Act 1 inferno fast, due to some good teamwork, and a lucky Hellrack Drop.
Died a trillion times in Act 2 but managed to push on.
Belial dropped me a crazy 1k dps xbow, on my first solo down.
This Xbow carried me through Act 3-4 in which i was able to farm gear for our barb and monk.
Now i am farming Inferno Cow Levels with a Witch Doctor and are able to progress and kill all elite mobs inside, minus the crazy combos of course :)
This is my build for the cow level, Caldrops for me is absolute requirement, it just delays charging ponies for that 1/2 second if u stand in middle or behind trap allowing you to use SS and run.
Tactical Advantage is a absolute must to cover some distance between yourself and the MOB, when in a team you can switch the hatred regen or valley of death rune on your Mark for Death
But if you have a group of friends that know what they are doing, we found farming the Acts 4 man, with Neph Stacks and Major Bosses always drop 3+ rares to be the best farm. Each run of Act 3 starting from Just after gatekeeper to Asmo, nets us 10+ rares. The best thing is for you to all ID and exchange gear for each other when it is a upgrade then sell the rest. That means as a Team you can get up to 40+ rares! Remember to rotate CDs and find synergy with each other! Ontop of that one slip up from yourself doesnt mean the elites will full heal, and to us thats the ultimate benefit of working in a team.
Anyways be glad to help with other questions! Going to catch some ZZZZ for now, hope you all have some good luck on ur rolls!
