I hate when the argument for not adding/changing abilities for PLD are denied because SE wants PLD to stay "simple".
Their PLD design was pretty simple in ARR, but when HW came out many abilities were added to push PLD away from the standard 1-2-3 halone spam.
Granted the play style is still more straight forward than WAR/DRK. However, this is the exact reason that gives PLD room to grow.
All in all, we wont see anything beyond more TP/potency adjustment until 4.0.
Other than the WAR major rework in 2.1, SE doesn't really add much to a class beyond TP/potency adjustment mid expansion
