I'm giving him grace, since he's still got bigger campaigns to write after Zhao. Long as the ending for Zhao is good, i'm satisfied with the amount of strategical arcs we've gotten related to Zhao, leaning more story-based to finish off the Zhao-storyline is fine with me tbh.
He's still got the giant campaigns of Chu to write, the massive Wei campaign. Also gotta save strategical showcasing for when the current gen becomes full generals, without just repeating redundant strategies (cause lets be honest, there's only so many new formations/tactics he can come up with atp).
But yea another arc like Shukai would be amazing, hoping Yan or Wei is that next big Shukai-like arc.
