I'm levelling my Guardian and Commando concurrently while I wait for the Kira bug to be fixed. The JG is at 38 and the Commando is at 34. As a result I can compare and contrast the same content while similarly geared, and the Commando is so much better/easier than the Guardian it isn't even close, and it has been this way from the very beginning (i.e. level 1) People white-knighting the JK class and saying it's okay have NFI. I'd find it hysterical if the disparity in class power wasn't negatively impacting my enjoyment of the game.
