Damage scaling is huge problem for melee. If I could glass cannon I would. As it stands I have 2 attack abilities, and four defensive abilities, and all of my passives are defensive.
So what you say is maybe true for ranged, but Act 2 is just brutal on my Monk. I've ventured into Act 2, but unless I get a really easy set of affixes on champ packs I just don't have the gear for it.
I sacrificed about 14k health, and 4k dps just to get 60% resist all, 70% dmg reduction from armor, and about 40% dodge. (I'm not really trying for dodge)
I am now finally in a place where I can farm 99% of what Act 1 Inferno throws at me. However in all my runs I have only seen 1 drop that has been an actual upgrade that helps me gear up for Act 2. What I need to start dropping is armor with dex, vit, and strong resists. Unfortunately what I need for my weapon, rings, and amulet involve atk speed which either comes in it's magic form with one other stat, or goes on the AH for 500,000 - 1,000,000 gold.
Almost everything I have has been bought through the AH. I have a legendary helm that was given to me that is pretty good, but the resistances on it are too low for me to keep it. I feel like every piece I have needs to have resist all or poison resist, but how low can I let my dps fall before it's all moot.
The reason the invisible hydras in Act 2 and the phase beasts in Act 3 are such a problem for ranged is that they can't kite them. With melee that doesn't really matter because you don't really have the option to kite in the first place. Sure there are some positioning tricks, but those don't matter when you are getting two shot.
So for now I am stuck farming act 1 until I get some decent rare drops with enough vit, dex, and resistance to upgrade my chromatic magic items.
To be honest I am sick of farming Act 1 already (doesn't help I've farmed the Skeleton King for months in the Beta). I am just about to call it quits until the first balance patch rolls through.
You won't farm gear in A1 that lets you progress through A2 and beyond. It's a completely unrealistic goal, and that's part of the problem. What may be vaguely possible is to farm money for weeks and weeks to buy the gear, but the gear that allows you to go further costs several millions per piece.
My barbarian is in that realm now: 10500 armor, 48000 life, 800ish in all resists, full defensive build, and I get killed in seconds even in the very beginning of A2. It's untankable for me. Yet the only things that are really upgrades for me are things like high-block Stormshield, 20% String of Ears, and perfect rares. They all cost up to or more than 10m per piece. It could take me many months of just running the fucking Butcher to get there, and that's simply not an acceptable expectation to impose on any player. As far as I can tell from my thorough stream-watching and research, the only barbarians who get to play in the later acts are people who have been absurdly lucky and found several multi-million gold items that let them gear up, or people like Kripparrian who have a dedicated team of 16h/day pro-gamers carrying him through content and spoonfeeding him everything he needs.
As it stands, it is effectively impossible to play through inferno as a melee class, it takes a completely unreasonable amount of time farming or the kind of luck with drops that one in a hundred thousand players have. With average farming luck and nobody to babysit you through the game, it looks like it'll take many months of farming just to get the gear that lets you start the journey. It would be retarded of me to stick with my barbarian for any other reason than an illogical desire to play a barbarian, because I could roll a ranged class and get way, way richer because I could be farming the later acts and doing it with 100k dps instead of 10k. You've probably seen the videos; Athene's DH kills inferno Diablo in 2 minutes, Krip's barbarian does it in 20. That's a serious problem and one that makes it literally and tangibly not worthwhile to play a melee class. There's a huge opportunity cost because the ranged classes make you so much richer.
The problem is not so much the direct price (though they are still a bit high) but the ludicrous amount of ingredients required to craft a high level item. I've got recipes that require more than 20 essence! Are they fucking mad? 20, plus another 50k on top along with rare mats, to roll the dice on something that will 80% be garbage, especially when I can buy a much better fit on the AH?
I don't think they'll find people crafting those high level items for anymore than 20-40k total cost, including all materials (which in inferno are currently selling for 2000 each).
