"Scoundrel and Commando for big heals"
Just to be totaly clear. Dont play the Scoundrel or Commando for anything other than heals in pvp.
You are food for the sharks as dps.
Disagree. While I don't play rateds on my Scoundrel and Commando, I have a lot of fun as a BM+Scrapper and Assault hybrid. Granted, the latter isn't perfect for 1vs1, but with proper movement and positioning, it can do very well.
