AFAIK the general assumption is that you will want to repair the node manually, within the GCGraceSeconds period. If this cannot be done then nodetool decomission and removetoken are the recommended approach.
In your example though, with 3 nodes and an RF of 3 your cluster can sustain a single node failure and continue to operate at CL Quorum for reads and writes. So there is no immediate need to move data. Does that help?
