What content to farm now?

[Game]

There's been lots of updates, lots of new content that I have no clue about, and I just now have an IK geared Barbarian(I also have a Warcry set, none of my gear is custom though) and I have no clue what to farm...

The barrier to entry into endgame content seems even more daunting because of the insane monster life increase...What should I farm to get gear better than IK? Just...Farm Duri for marks all day long?

ALSO: With the Whirlwind buff, is it better to go WW or Shieldthrow with IK?

I'd be more than willing to change class completely, Barb may not be the best starter for basic MFing....I know that Mav zon is really good, Necro etc. I just really need some guidance, I LOVE this server, but it's so confusing...I wish more people made video guides about it..

You can get very high end gear from other places rather than just puzzles. IK set is very starter, you can do ilvl 87+ area such as the pit in act 1 or the inferno portals in act 5 and find things like grandfather, arkaine's wrath armor, and much much more. Whirlwind is in a good spot right now for sure.
