I have too noticed the crappy hitbox problem where, when an enemy starts an attack on you, you will get hit no matter where you are when the animation actually hits... Bashiok says::

It's intentional. We don't want a game where the most effective way to play is to dodge in and out of enemy attacks. It's not that difficult to do, and it's just not a very fun way to play. "Most effective" and "not fun" just can't be in the same sentence when describing part of the game. We want combat to be based on use of abilities, putting thought into builds, building up offensive and defensive stats, etc. Skill is absolutely a part of all of the systems you'll use, and kiting can be too, but it'd be ridiculous if you could avoid all of the systems that make the game the game because you can time dodges of enemy attacks and negate every other factor.
Also think about just running past enemies to rush through an area and never being hit. Anyone looking to rush would love it! Which is why it's not a good idea from a design perspective.It's not something we'll be changing.
