We're all capable minded people who will see the warning upon hardcore creation and know what we are getting in to. Forcing us to go to soft core delays us from playing the game we want to. It prevents us from starting the characters we intend to keep( hopefully) and building up our artisans and stashes.
Blizzard, give us the option right off the bat, we've waited a long time for this game. Let us jump into the game we want, not one we have to rush through to "earn".
