If your goal is just to complete the content, rather than to farm or anything like that, consider swapping some of your dps oriented pieces for pure tank pieces. Get your resists up over 1000, and swap to a shield with better armor, block value, and block chance, etc. And then spec even more defensively than you have: http://us.battle.net/d3/en/calculato...SkP!bVe!aacccZ
If you can afford it, life on hit is of course excellent, and if you get a decent amount you could drop charge out of the above build in favor of ignore pain or earthquake.
Pure tank barbs can get through the entire game on pretty modestly priced gear (300-500k will do it), but you have to give up all pretense of being a DPSer. Trying to be a hybrid tank/dps is almost certainly what is causing you problems.
Pure tank barbs can just tank through enrage on elite packs, so don't worry about that. Worst case you drag the pack to a bunch of trash so you can use charge/revenge to heal.
Bank your crit gear, and find a cheap LoH weapon for Ghom. You'll spec crushing advance for that fight, and stand in the gas. You'd never beat the enrage trying to play it straight up.
Well the crit gear is nice to have for certain fights (ghom) but if you need to sell it in order to be able to afford better tank gear, then you should. Ghom can be done with base crit chance (you can get 20% just from passives), so if you need to sell it in order to afford the tank gear, do it.
Keep in mind that I make this recommendation only on the assumption that your goal is to complete the game without doing much/any more farming. If you want to farm gear you're better off sticking with act 2 farming and higher DPS gear.
magicrectangle I really appreciate your help and I am sorry for all the noob questions, but please if you could give me a bit more advice I would really appreciate it.
(a) I do want to finish the content BUT
(b) If my gear is good enough to farm act 2 (Is it?) THEN
(c) I would rather finish the content slower but have a better character at the end who can farm act 3 SO
(d) What would you suggest strategy wise, gear wise, build wise etc?
Okay well if you don't mind farming a2 for a while, I'll rescind my recommendation of a tank spec, and instead suggest that you're not too far off from being able to do act 2 as a whirlwind barb. You have decent crit chance, decent life, decent resists. The big thing that you are missing is life on hit. If you traded in your shield for a low dps dagger with 800 LoH and a socket (crit damage gem) you would be pretty much set for whirlwind farming act 2. You would not be sufficiently geared for whirlwind (farming or otherwise) in act 3, but you could start working your way up to it gear-wise from there.
edit: your armor does seem a little low. With the aforementioned dagger you would destroy act 1 at a very fast pace, and that would probably be better loot/hour for you than a2, as some packs might still give trouble in a2 with such low armor (subtract the shield and it seems very low).
Wow, thanks so much for the advice. Unfortunately I am on the EU server, but I will look for a dagger as you suggested and I think I will WW Act 1 for a while to earn cash. Can I ask your advice regarding saving up gold?
Should I just vendor everything, vendor everything below ilvl61 and salvage everything above ilvl60 and sell the essence? Should I only keep ilvl63 for the AH?
Blues below ilvl 61 get vendored, except for jewelry and follower tokens, those get vendored under ilvl 60. Higher level blues get salvaged for exquisite essences.
Bad yellows almost always vendor for more than the value of their salvage components, so vendor pretty much all of those, and just save what might sell on the AH.
As for what sells on the AH, that would be a huge list. Suffice to say anything ilvl 60+ can potentially sell, with the right mods. You should absolutely identify all your yellows at this stage of progression, and AH the ones with promising stats. If it isn't good for one of the popular builds, keep in mind it won't sell for much, but you can still get 10k-20k for stuff that is just as simple as primary stat + vit + resist.
