Laravel unexpected redirects ( 302 )

I have started a new Laravel 5.2 project, using laravel new MyApp, and added authentication via php artisan make:auth. This is intended to be a members only website, where the first user is seeded, and creates the rest (no manual user creation/password reset/etc).

These are the routes I have currently defined:

 Route::group(['middleware' => 'web'], function () {
  // Authentication Routes...
  Route::get( 'user/login',  ['as' => 'user.login',     'uses' => 'Auth\AuthController@showLoginForm']);
  Route::post('user/login',  ['as' => 'user.doLogin',   'uses' => 'Auth\AuthController@login'        ]);

  Route::group(['middleware' => 'auth'], function() {
    // Authenticated user routes
    Route::get( '/', ['as'=>'home', 'uses'=> 'HomeController@index']);
    Route::get( 'user/{uid?}', ['as' => 'user.profile',   'uses' => 'Auth\AuthController@profile' ]);
    Route::get( 'user/logout', ['as' => 'user.logout',    'uses' => 'Auth\AuthController@logout'  ]);
    Route::get( '/user/add',   ['as' => 'user.add',       'uses' => 'Auth\AuthController@showAddUser']);

    [...]
  });
});

I can login just fine, however I'm experiencing some very "funky" behavior - when I try to logout ( via the built-in logout method that was created via artisan ), the page does a 302 redirect to home, and I am still logged in.

What's more, while almost all pages (not listed here) work as expected, user.add also produces a 302 to the home page.

Do note the homepage is declared to the AuthController as $redirectTo, if that makes any difference

I found out about the redirects via the debugbar. Any idea on what to look for ?
