You can extend system router as per requirements,

1. Create My_Router.php in application/core/ directory

/**
 * Description of My_Router
 *
 * @author girish
 */
class My_Router extends CI_Router {

    //put your code here
    public function __construct($routing = NULL) {
        parent::__construct($routing);
    }

    protected function _set_default_controller() {
    if (empty($this->default_controller)) {
        show_error('Unable to determine what should be displayed. A default route has not been specified in the routing file.');
    }

    // Is the method being specified?
    if (sscanf($this->default_controller, '%[^/]/%[^/]/%s', $directory, $class, $method) !== 3) {
        $method = 'index';
    }
    if (is_dir(APPPATH . 'controllers' . DIRECTORY_SEPARATOR . $directory) === true) {

        if (!file_exists(APPPATH . 'controllers' . DIRECTORY_SEPARATOR . $directory . DIRECTORY_SEPARATOR . ucfirst($class) . '.php')) {
            // This will trigger 404 later
            return;
        }
        $this->set_directory($directory);
        $this->set_class($class);
        $this->set_method($method);
    } else {
        if (sscanf($this->default_controller, '%[^/]/%s', $class, $method) !== 2) {
            $method = 'index';
        }
        if (!file_exists(APPPATH . 'controllers' . DIRECTORY_SEPARATOR . ucfirst($class) . '.php')) {
            // This will trigger 404 later
            return;
        }
        $this->set_class($class);
        $this->set_method($method);
    }
    // Assign routed segments, index starting from 1
    $this->uri->rsegments = array(
        1 => $class,
        2 => $method
    );

    log_message('debug', 'No URI present. Default controller set.');
   }

}

and overwrite _set_default_controller() from custom method, it will work from sub-directory controller as well root directory controller.

And in application/config/routes.php

if you need sub-directory default controller, then

 $route['default_controller'] = "admin/admins/login";

• admin -- folder
• admins -- controller
• login -- method

if you need root-directory default controller, then

 $route['default_controller'] = "welcome/index";

• welcome -- controller
• index -- method

not sure it will work in all versions, but tested in CI3.0.6
