Environment - Non Weather Related; Procedure
Strong wake turbulence encounter into LAX. Approximately 6 miles spacing from lead as referenced via TCAS. Encountered 'limited aircraft control' because of event; immediately requested vectors off course for 'clean' air. Encounters are much more frequent since the implementation of RECAT (Wake Turbulence Recategorization). Things need to change; spacing is too tight now. No need for pilots to have to deal with this issue which can possibly create severe safety concerns.
Reporter stated that 'ReCat is a disaster' and in his opinion spacing must be increased for safety.
