This arc has been going on for 7 issues. In that span, we've seen Eggman test, unleash, and lose control of a plan. We've also taken inventory on the cast while the fallout is occuring. So far, it's a steady pace for a story. If it drags out longer than 12 issues, I'd agree. But for now, it feels about right. I'm not sure if Shadow being turned is more of a sign of his appeal, or his unimportance to the series at large at this point .
