that's not how comic series work. a reboot is something like the new 52. a new comic run and a reboot are not the same thing if they were spiderman would have been rebooted like 7 times in the last 3 years.
this is also comply untrue. fem thor kept steady sales and was planned to be temporary before she ever had the hammer. Iron heart was never meant to stay they made ti clear even in civil war 2 that tony wasn't gonna be gone for ever. Cho wasn't the first time the hulk was gone and no one thought he wasn't coming back.They were only temporary because the comics failed and caused them to go nearly bankrupt. They were series reboots.
did you actually read any of these comics or even the comics that came before them?
