No to a reboot, I'm actually enjoying some of the evolutions of the characters such as the Doc Green business, Flash Thompson as Venom, Eddie Brock (when he was Anti-Venom. Gone too soon), Deadpool and Daredevil's current statuses. Several of these stories would never work immediately after a reboot. It would have to be a long trek to get there, or they would be too early in the character's history and lose impact.
Case in point, I hated Red Hulk when he first showed up, but under Jeff Parker's treatment, I loved the character and was sad to see him lose his book. It worked as a story of growth, humility and adaptation for ol' Thunderbolt, and such a story may not be reproduced at all in a reboot, or if it is, it'll take yeaaaaaaars to get there, and I'd rather that not happen.
What even needs to be fixed by a total reboot anyway? If anything, it's the moving forward that needs fixing. Slow down on all these huge events. Nothing kills the pace of a story for me faster than having a personal journey uprooted because "Oh hey, we're all fighting each other again!" or "The multiverse is in danger for the 4th time this month! It's slower than usual, but you know the drill!"
Have arcs, have journies, but but not everything needs to be company wide, so that when it does come time for such an event, it builds and leaves an impact.
Reboots aren't going to stop the current issues that bother some readers, so if anything gets "fixed" it is in danger of unraveling quick.
Heck, I'm not even really looking forward to Secret wars for the sole fact that it's going to change things for like 6months rather than just a summer or winter event. I don't know how it'll effect things like Punisher, Daredevil, Deadpool and other characters that I read who aren't currently plugged into the huge Avengers situations.
Also I echo that not everyone needs to be an Avenger. I like the MCU, I really do, but not everything needs to be folded into their ranks or adopt the name for sales.
*sigh* I'm sorry for the rant, I feel like a cranky old man, despite being on the cusp of 30...
