I actually like the idea of a space marine wearing a sort of ablative armor over suit to help get the marine across the battlefield that could be shed if it becomes too damaged or impedes the wearer. However, the model itself doesn't look very pleasing to me, and I agree with others that it tries to steal the role of Terminators and Dreadnoughts both of which could have used better rules to make them do the job they are intended to. Push come to shove, I would rather field either or both Terminators and Dreadnoughts over Centurions even if the model was nice looking (and available to
CSMs).
