Often a common-collector will be the last stage before the load; the main function(s) of this stage is to:
provide voltage gain
provide phase inversion
provide a high-frequency path to improve the frequency response
buffer the voltage amplifiers from the low-resistance load and provide impedance matching for maximum power transfer
