Yeah in all actuality, Diablo 3's skill system makes it seems like Diablo 2 had no customization... mostly because with Diablo 2 there was only the "illusion of choice" because if you didn't use proven builds that were proven to be viable and/or optimal using spreadsheets then you would have a rough time in Hell difficulty. You couldn't just play around with skills and use the ones you thought were most fun because in the long run that build most likely wouldn't be viable. In Diablo 3 you can experiment without needing to research a builds viability and there are so many combinations that you'll never run out of options. You can make a melee wizard if you want, an AOE barbarian, or a pet-less witch doctor... etc etc. So there is a lot more build diversity and given all of the combinations it will be a lot more difficult to argue that X, Y, or Z build is the most optimal build.
Overall Diablo 3 looks amazing and I can't wait to play it in less than 11 and a half days! :D
I am elated to know a date - 2 months is usually pretty short - but with this news in the back of my mind at all times I know that time is gonna drag even more slowly. Hooray! We finally got a release date!
Cutting PVP for a quicker release is fine with me since the core game is still in tact. I can't wait for Diablo 3 much longer so knowing it will NOT be delayed further is a rather welcome surprise from a company like Blizzard.
