People who think the green K turn would somehow shatter the earth with it's overpoweredness aren't going to be worth listening to, honestly. They aren't good enough at the game to know what's going on.
Things that are really really good in X wing:
Big turret ships
Phantoms
12 point ships
Things that don't care if a ship can green K-turn:
Big turret ships
Phantoms
Things that will block a green K-turn, turning it into a green straight with no action:
12 point ships
Make the K turn green if you want, it won't matter. For the points a loaded defender costs it wouldn't be OP if the whole dial was green. It would be thematic too.
Yeah, no. Saying that making the k-turn green would fix the Defender is about as valid as saying the green k-turn would be overpowered. I don't like the green k-turn because it would opens up the debate for white k-turns being more accessible. The White K-turn is pretty powerful, and it should be rare.
People don't like the dial. That is a perfectly fine opinion to have. Not all ships will fit to everybody's play style. Just stop trying to make a Defender into a different type of ship. I love its dials and its options. I'm sorry that the Defender can't the super ship it was introduced as in TIE Fighter.
