I think this is in response to the "homework problem" you often see people complain about for the MCU. I'm not convinced it's a real problem, apart from Wanda's storyline, but perhaps behind the scenes it causes more issues.

It'll be interesting to see how some non-Gunn lead stories shake out in the coming years. "Man of Tomorrow" will reportedly have both Guy Gardner and Jon Stewart in it. How will that affect a future season of Lanterns?

Also just the practicality of it all. Is Tom Rhys Harries (Clayface actor) just supposed to chill until his character is needed again? I guess I'm fine if it's a one off. And as we saw in the MCU some actors will just stick around for a while and ultimately do very little (e.g. Maria Hill).
