When you read or write data, Cassandra computes the hash token for the data and distributes to respective nodes. When you have 3 node cluster with replication factor as 2 means your data is stored in 2 nodes. So at a point when 2 nodes are down which is responsible for a token A and this token is not part of node 3, eventually even you have one node you will still have TokenRangeOfflineException.

The point is we need replicas(Token) and not the nodes. Also see the similar question answered here.
