After Avengers 3, and IM/Cap/Thor finish their trilogies, more Avengers or Phases without Evans, Hemsworth, and RDJ are going to lose most of their luster. You have to build up the anticipation again. Solo movies with new leads would especially be lack luster after an Avengers trilogy.
I don't agree that you have to reboot though. But outside of Thor, most of these characters get older. Captain America may age a little slower however, so it's easier to recast him.
