I very much disagree with this. My very first build, without looking at any build sites was a Fireball sorc, and I made it up to Act 2 merciless before that league ended(this was about a year n a half ago). I've since made several builds since and I've yet to have to abandon a build due to it being terribly inefficient. Even if you do mess it up some, that's what Orbs of Regret are for, + all the passive respec points the game gives you naturally. It's not had to fix a minor problem here or there without having to entirely restart your character.
