Worth watching the rest of the Series (just finished episode 54 season 2 finale) if Yang is my favorite character?

I understand that Yang Wen-Li didn’t technically lose the final battle at the end of Season 2, but I can't help feeling frustrated that he didn’t just take out Reinhard when he had the chance. Now the FPA is conquered so I'm curious on how there's still 56 episodes left. There’s still half the series left, but as someone who resonates with Yang the most, I’m wondering—without direct spoilers—is it still worth watching?
