The Escort Carrier is great from a mission standpoint because it can realistically deploy numerous waves of Ties, and it's far more vulnerable to fighter attack than an ISD. Only problem is how damned ugly it is...ideal candidate for a reimagined version? Yeah the Combat Escort Carrier is a much cooler looking ship, but its size means that the fighter complement probably isn't all that different from a Carrack, so it might be a bit redundant at this stage. Not that it isn't cool to have multiple ships with similar capabilities, but we still have major size gaps to fill in the cap ship department.
