Suugen shouldn't blame himself , if there's anyone to blame it's Shin, he's the one not doing enough . how can you hope to be a great general if you're 10,000 man army falls to pieces just because 2 people are missing , so I should just kill this one infantry commander and the rest of the dominos will fall apart.
This isn't a tea party , and if you're lacking competent officers , request some veterans. Why are you ponding over the new recruits.
