Wow, whare to start, there are so many wrong things about your stance, and perception of gameplay.
I'm no SC fan either, but there is no way in hell, a move to 3D graphics, without completely changing the game along with it, is a good thing.
If anything has been proven, time, and time again, is that in every single case, 3D actually detracts alot from gameplay, unless "every" single system is built from the ground up, to make use of 3D, and even then, the game would most likely suck compared to a 2D counterpart.
D2 is not 3D(did you really spend endless hours playing D2?)lol, so I really don't know where you are getting at.
I really hate it, when I need to help a person, that I'm against, make his argument. Well anyway, you should've mentioned DDO instead(Dungeons & Dragons Online), that's probally the best example there is, when talking about how good a 3D game can be
