I've had some good experiences with Madine keeping a ship alive, for example to slip out of a blockade trying to trap a large base or dodge out of the arc of something scary. If you're first player though, you should already be able to double arc a ship, shoot it, and then leave. Madine doesn't really make that any better so I haven't found much improvement on the shooting side of things. If you're running away from squadrons instead of ships he also doesn't help, and a bunch of rogue squads will ruin your day. If you bring a bunch of your own squads Madine has fewer ships to help out so you may start to wonder if Rieekan wouldn't be better. Rieekan or Agate also allow you to fly more aggressively because removing your ship(s) is a bit harder. If you just want to womp your opponent's ships as fast as possible then Raddus is probably more helpful.
Maybe if Madine's token effect was more powerful he would free up your command dials to do something else, but as things are I don't often feel like I get 30 points of use out of him.
