Can we try to avoid a giant flamewar just this once?This is tuned toward Barbs reaching 60, finishing Hell, and getting stuck on the difficulty.Let's try to categorize the useful skills, the useless skills, the best strats at different phases of the game, etc.I personally find the following spec the best all the way through Act 1 Inferno (including Butcher runs)2h Elite/Boss killing spec/gearing spec0. This is your spec. Try not to deviate. http://us.battle.net/d3/en/calculator/barbarian#WViRPk!bVZ!acabZc I prefer ruthless to Zerk Rage if you have good crit. Otherwise go Zerk Rage.1. Buy yourself a 900 DPS 2h. They're going for ~150 on the AH. You get > 500k just from levelling, so don't tell me you can't afford it.2. Use whatever gear you have currently. With the weapon from 1, you have enough gear for Act 4 hell diablo runs, even if the rest of your gear is garbage3. At around 400 resists 6k armor, go to Act 1 Inferno and do 5 stack neph butcher runs4. Start acquiring MF gear. You can safely wear 100-150% MF depending your gear and still do the runs5. At this point I'd honestly just hoard gold. If you can save up 5-10 million, and wait for the coming price crash on items, you'll be able to buy a ton of top end loot for cheap6. 800 res 8000 armor and roughly 40k hp will be enough to move into Act 2 Inferno, sword and board recommended but you can make 2h work there as well if you zerg fast enough on elites.Stat priorities:Str=Vit (keep it 1 to 1 when possible), try to keep health above 30k at all times, 40k+ is nice, 50k+ is not neededAll resistPhys ResistEverything else (armor etc)For your weapon, I recommend whatever is highest DPS. That'll usually trump other stats, but sometimes you're really vit starved.Life leech is garbage in Inferno, since it's 20% listed. 2% listed life leech is 0.4% life leech, which is just not noticeable. Ironically, 'on hit +X life' is much better, since that can be 500-1000 per hit on high level gear, which can heal you fairly rapidly in frenzy.*sidenotes:Contrary to public opinion, the following 2 commonly used skills are worthless on barbarians and should never be taken in any circumstancesBloodthirstSuperstitionThe first does NOTHING on Inferno (it's nerfed to the ground), so don't botherThe second prevents damage that you can dodge yourself, so it's also worthless. On inferno, physical damage is much higher than magical.Finally, Frenzy Sidearm is flatout superior to Maniac. Play them both, and you'll see the difference. It's staggering.
