Doing reads and writes at CL=1 with RF=2 N=2 does not imply that the reads will be inconsistent. It's more complicated than the simple counting of blocked replicas. It is easy to support the notion that it will be largely consistent, in fact very consistent for most use cases. By default Cassandra

You'll need to either read or write at at least quorum to get consistent data from the cluster so you may as well do both.
