The big worry, of course, is whether those builds are viable at all levels. You don't get a feat until level 4, after all. You don't get your fighter archetype until level 3. On the other hand, it seems intentional that the first few levels should get pretty quickly - and are even perhaps deliberately less defined, so that you have a few levels before really having to decide where to focus one's build. I'll wait to see how that plays out.
If I recall correctly, experienced players are advised to start at level three so they can just incorporate their archetype straightaway. This also makes the first level up an interesting situation, as you can take a multiclass level, or stay in your class and get bonus attribute points, or stay in your class and take a feat. Even if you start at level one, however, the first two levels are really, really quick.
An added - and likely intentional - benefit of having archetypes kick in at class level three is that it limits abusive multiclassing. Whether you start at level one or level three, you're going to get your "home" archetype very quickly/immediately, but getting a second archetype takes a very big experience investment, especially when so many class features scale to class level.
I do think the 5E feat system is going to lead to many more human characters, though, as humans can take a feat straight off the bat, and many players are probably going to favor the human's "two ability points and a feat" rubric over the other races' "three ability points" rubric.
