Diablo III Game Design Update, Lots of Changes Incoming

It appears that Blizzard Entertainment has taken a lot of player feedback to heart since the release of Diablo III, as this new design update over on the game's official website outlines some of the changes they're planning for character skills, crafting, items, game balance, and more. There's a lot of info to take in, so I'll quote a significant portion of it:
Inferno is intended to be extremely difficult, but with some specific skills, a few classes were simply able to progress far more easily than intended. This made the classes, which were about where they were supposed to be, seem very underpowered. It also created the perception that the classes doing well were intended to rely on specific runes in all their builds, and the other classes were just broken. This is the opposite of what's true. If any single skill or rune feels absolutely required to progress, it means that skill is working against our goal of encouraging build diversity -- and those (required) skills need to be corrected. We know these hotfixes snuck up on people, and it took us a day or so to communicate that they had gone live. However, our intent moving forward is that when there are circumstances where a hotfix is necessary, we'll  communicate changes that could impact your ability to play your class through '˜Upcoming Changes' posts in the General forum. Ideally, we'll let you know as soon as we even have the idea that we want to make that kind of change.

That said, we also wanted to let you know we're keeping a close eye on Inferno. The intent of incoming damage is that it should be a very consistent drain on your health, and mitigating that drain is a major part of what makes Inferno mode difficult. Right now, there's a lot more damage (spikiness) occurring than feels right, and that's one major area we're looking to adjust in patch 1.0.3. While we don't have any specifics yet, our design goals are to support and promote build diversity; continue to ensure that a mix of champion packs, rare packs, and boss fights are the most efficient way to acquire the best items in the game; and ensure that all classes are viable in Inferno.

From a high-level perspective, we think a more fundamentally fun way to approach difficulty in Inferno isn't seeing how much incoming damage you can avoid or mitigate, but rather to see how efficient you can be while voluntarily taking on a challenge that pushes you. For anybody who's ever died because they chased a Treasure Goblin too aggressively, you know what we mean; dying because you got greedy or overconfident can actually be a lot of fun. Now that the skills mentioned above have been brought more in line, we'll be keeping a close eye on balance.

We've also seen some people saying our intention with Inferno is just one-shot you to make it difficult. While damage is a bit spikier than we'd like, we're actually seeing a pretty significant number of people attempting Inferno without sufficient gear. There's a good chance that returning to the previous Act to farm upgrades will do the most to help you survive. That said, we'd like to shift some of the focus away from survival and more toward using a variety of offensive tactics to succeed. Survival will still be important, but finding ways to maximize your damage while staying alive is more exciting. We're not particularly concerned with whether or not a boss is (beatable,) though it should feel epic and challenging to defeat it. We're more concerned with ensuring that acquiring 5 stacks of Nephalem Valor and taking on as many Champions and Rares as you can remains the most challenging and rewarding way to play.

On to items! One of the biggest pieces of feedback we've received regarding items is the relative power of Legendaries. This isn't a simple issue to address, as it involves some intentional design decisions as well as expectations built by other games. First and foremost, Legendary items are not designed to necessarily be the best items in the game. They're just one additional type of item as you level up, and they are not meant to be the primary items you're chasing at the end-game. They can -- and should -- be exciting to find, but they're not supposed to serve as the single driving force of the item hunt. Rare items, for example, have the possibility to roll up (perfect) stats that can, if you're lucky, outpace the predetermined stats of a Legendary. That's by design.

One problem we've seen -- and intend to correct quickly -- is players comparing high-level Magic (blue) items to lower-level Legendary items as (proof) of an imbalance. To help correct misconceptions of the actual stat budgets allocated to items, we'll be exposing item levels (ilvl) of 60+ items in patch 1.0.3. Comparing an ilvl 63 blue to an ilvl 60 Legendary will hopefully make a bit more sense afterward. In addition, we're planning to just straight-out buff Legendary items in a future patch, likely the PvP patch (1.1). These buffs will not be retroactive, and so they'll only apply to new Legendary items found after the patch. In the long term, we're looking at simply expanding the affix diversity and unique bonuses of Legendary items, and we'll be able to share more details after the PvP patch.

Other areas of concern have been both the gem combination system and Blacksmith leveling and crafting costs. The intent, especially with the Blacksmith, is that he's leveling with you, you're able to use him as an alternate source for upgrades. Our design goal is that once you get to level 60, his recipes are actually good enough to help fill a character's potential itemization gaps. To correct these issues, we're looking to adjust the Blacksmith costs for training (gold and pages) and crafting from levels 1-59, and reduce the cost of combining gems so that it only requires two gems instead of three (up to Flawless Square). Both of these changes are scheduled for patch 1.0.3.
Even with the crafting changes, I highly doubt I'll spend any additional money on upgrading my artisans. Gold just goes way farther on the auction house.
