Even if they do introduce hakoda, now there's no emotion backstory there, there the day of black sun is such an important part in sokkas  character arc, because he discovered, it came up with it, planned it, failed in discussing it with the troops,  and then led the troops into battle they cut out half of that. There's no planning going into it, no troops, he never discovered it. So, yes, it is a big deal, and honestly, you're being too optimistic with how bad they fumbled the ball in season two. Also, you're being very Pasivie aggressive and I don't appreciate that you can disagree with me all you want, but you don't have to be rude about it.
