Duckroll, alright.
The matter is very simple for me. It is this: yes, I believe that Blizzard has the ability and the talent to provide us a customization system that is meaningful, that is an added layer on top of everything that is already awesome in their game. The main difference between us whether the inclusion of that imaginary system or the non-inclusion makes a difference at the end of the day.
I have been reading some posts in Diablo.Incgamers (I know, I know, my fault for going there

), where people expressed that with speccing into something, they knew that they "achieved something that is not possible for others". That by getting a very specialized build working, they were unique to the others. Ultimately, I do not share this and was quite literally shocked by this: I mean, if our fun factor solely depends on "how many others are able to enjoy it simultaneously to me?", then we are doing something WRONG, imho. Where were these people and what were they doing before video games? o_o
But before I dwell in that for too long and you call on a "strawmen" again (which is nonsense, anyway), let me just say that the main difference between you and me is this: I recognize that ultimately, we both will play with the skills that we enjoy the most. We will both play the builds that we like, we will both build our gear so that we will ignore +1-2-x damage modifiers on skills that deal ONE huge damage instead of a lot of tiny chunks, and will gather +x damage modifiers on skills that do a lot of different small damage chunks on a lot of enemies in fast succession. The difference then is simple: Whether we call the things that lead to the point where we enjoy our preferred builds "dumb", "streamlined" or simply "simplified" or even "restricted".
In my few D3 beta playthroughs yesterday, I have on all the classes encountered skills that I did not even get to try, as I was trying to work on my current "skill combination", I levelled up, and a new skill came, and suddenly, I could not cram 4 skill into 3 possible slots, or 5 to 4 slots. There will be things to experiment on at every level, and even at lv60, when we get to access the more unique affixes on items, I believe.
So, to summarize: there are TONS of ways that our imaginary Diablo 3 could definitely feel more interactive and more customizable than the one that is going to ship sometimes in Q2. And I agree with that. All I am arguing about whether that additional layer really is a necessity for a good, enjoyable, timeless classic. I think it is not. And I also think that we do not know how they are planning to expand this. If their main goal is to provide a new stepping stone for all the millions of players out there who grew up without and Diablo gameplay experience, than this is a good start - one that can easily be expanded with new, additional and really meaningful customization options in the future expansions and content patches, if Blizzard feels like that is what they need to do.
After all, after WOTLK's heroic (which was tank and spank, basically), everyone believed that they will NEVER go back to a harder system. And yet they easily switched back to the more challenging, more serious heroics like in Cata, even if thanks to the new items, the difficulty has decreased. But that is not in direct response to your post in any way, just my two cents to the matter.
