For pure PvE rape I'd go with 1 PT 3 Sorcs.

For pure PvP rape I'd go with PT's Sentinels or Juggs. The autofollow fix MIGHT readjust this but charging/leaping makes all the difference and mashing your follow while meleeing people down mitigates most of the follow issues.

Marauders also put ou relativelyt extensive self/group healing. Right now my usual DPS/healing numbers while playing a very objective centric playstyle is 200-250k DPS and 50k healing per Sentinel (not including my reusable rakata heals)

Personally my next project is going to be either double Vanguard (powertech) or Vanguard/Scoundrel to attempt hardmodes with DPS companions.

I am also relatively certain we can get sort of a ghetto IWT going for PvE melee DPS trains having melee DPS follow your tank and assist off of your tank! PT/Jug move via charge, and DPS adjusts likewise but will also follow if their charge is not up.

This would let you drive an all melee team in PvE with your healer which in my perspective would be the ideal method to control a team as you get the best situational awareness.
