I loaded him up with gear, and here are my current stats: http://imgur.com/UXCPK
10.3k armor (77.5% dmg reduction)
~800 all resist (~73% dmg reduction)
27% block chance (1.9k-2.8k dmg)
7.84% ranged dmg reduction
Using the typical defensive skills and passives, I can survive pretty well against most enemies in act 3 by constantly healing with skills, but alot of mobs give trouble. In act 4, I can survive a decent amount of regular mobs but elite packs are nearly impossible, since to get this much survivability you have to sacrifice a ton of dps. I can get my damage to ~18kish with my tank stuff and a damage skill up, but it isn't really enough to matter. My DH can just run and hit for 150-200k endlessly, and my barb can tank for 30 seconds and hit for ~20k. My monk with super gear was still garbage in act4..so I won't get into that.
So basically, even with REALLY high stats, barbs still get destroyed in act4.
Has anyone come up with a high dps build that somehow offers survivability too? Because from what it looks like, it is completely pointless to play meelee in this game.
So to anyone who says "you just need gear"..no you don't. I have the gear. Barb still sucks.
