It is still a good idea to level your defense but it isn't near as important as before. You won't be crushed even with a defense at 1.
Actually, you will get crushed if you're 20 skill points below the mob that's hitting you. I have a brandy new level 60 Pally (thank you RAF) and was getting crushing blows from level 9 mobs outside Orgrimmar. I don't think it's the level difference that matters but rather the difference between melee skill and defense skill. At least that's what I've experienced over the years. I could be wrong.
