Comparing it to wow is downright ridiculous. Wow has more quests or other content per square-inch, than all acts of diablo 3 combined... It also has competitive things like pvp. Large groups of people that have to coordinate, to take down a boss. Which will give you rewards and is challenging. That said, you simply can't compare it in that way, because wow is subsription based...
The comparison with diablo 2 is also lacking. The lootsystem is just so far apart from d3. I know four different runs in diablo 2 and I haven't even played it very much. There are plenty more if you want to hunt a specific item. In diablo 3 there pretty much is only one.
Diablo 3 is far from a bad game by now, but leaves much to be desired. There are things that can be improved and only if people open their mouth, can blizzard make good decisions on what is needed, to make the players have more fun playing.
If you use the ah, by now you can take any char and 100k gold and finish inferno easily. It won't be fast and you will die a couple times, but it's doable. Take 10 mio and you can clear mp5, not fast or particularly safe but it's doable. with 1 bio you can clear mp 10.
But even now with mp 0 being really easy, you might not be able to clear inferno selffound after several hundred hours of playtime. To get from mp 0 to mp 5 selffound, i would guess, takes around 1000 hrs of playtime selffound. I haven't found a single item that was better then what I allready got through the ah in 400 hrs playing my monk. So I think 1000 hours is a pretty low figure. To get from mp 5 to mp 10 selffound? Not in a lifetime.
So you can choose. Use the ah and have an easy game or don't use it and have an impossible game. It's just bad design.
"...so to the complainers, they are listening to you, but they will be less likely to take your complaints seriously when you come across as a whiny b**** rather than a sensible, educated, mature individual.
If you are incapable of getting over a flaw or challenge in a game by adjusting your character/gameplay, you really have no business playing a game in the first place. In my honest opinion, there is nothing wrong with this game. It is perfectly fair and provides a reasonable challenge. If it wasn't hard, it wouldn't be called Inferno. You can sit here and say that the game is broken, but what I really think is that YOU are broken. Use your minds and stop trying to get Blizzard to make a game that plays itself for you, rather than you playing it. Try it sometime, it's addictive."
Yeah you sound pretty sensible, educated and mature... But you have a point there. Some people just don't know how to formulate ideas and possible changes with a good manner. The problem is not that it is too hard. It is either impossible or far too easy. Well you could say, then up the mp-lvl. The problem is, that the rewards don't scale up accordingly. To put it in another way: My reward for getting better, is to play slower and therefore getting less loot and thus even less rewards for playing. From a loot point of view, mp 0-2 is still the most rewarding. Also bad design in my opinion. When there is a flaw in the game, it is far better to fix it at the core. It will be fixed one time, instead of every player having to find a workaround that works for him.
You say that you have played inferno on other accounts. Did you grind it out with act 3 a hundred times? I have done it a hundred times and then again and again and again. And that doesn't even compare to other people that have easily played double or triple my time. I have nearly killed as many elites as you have killed monsters. So yes I and many others have a better educated opinion of what the endgame is and what could be better. Hell the game would instantly be a lot better, if i could just grind in act 1,2 or 4, but I can't because Act 3 is much better loot-wise.
Diversity in builds? Hmm I can only speak about monks and we have pretty much two builds. One that is cheap and somewhat slow. The other one is very fast and very expensive. PvP will in fact not change that, because to get equip, you have to farm. Even if you use a different skillset in pvp, until you have bis, you will have to stick to these builds. Well I guess at some point it just doesn't matter what skills you use, jst because your equip is good enough.
The game is good. I have 700+ hours on the clock, so I must have found something good in it. But at some point it just gets boring and unrewarding. It could be better and will hopefully get there in time, but for now it has serious flaws that need to be adressed.
