I like Nova Squadron Radio, but I find they are quick to fall prey to the "meta" and dismiss things out of hand. They just trashed the Tie Bomber when I think there are uses for it. Still, a good show. Just keep an open mind about things.
Well, there is slightly more thought that goes into it than simply "it's not being used right now so we will just dismiss it".
Hopefully the math fundamentals on the show help to shed some light on explaining why the meta is what it is. Thanks for listening!
Related to the OP, Decimators can be played many different ways, with a lot of different support ships. Some crew are really good and should be at least considered in any build (like Isard or Rebel Captive). The best advice is to try building something, put it on the table and learn what you like or dislike about it!
