title: What are the advantages of MVC 5
body: <p>Are there any advantages that should motivate an established MVC 3 shop with a full stack to upgrade to MVC 4 or 5?  We've been using MVC 3 for quite a while and don't feel like we really need "new functionality".</p>
  
  <p>I'm looking for the type of advantage the Razor brought to views when MVC 3 was introduced over MVC 2.</p>
