You're ignoring half your class (DPS abilities) and complaining that your toolkit is too shallow. It's like saying bard adds nothing new to the class because you don't believe in playing songs.

Much as you don't seem to like DPS, doing DPS is your answer. Developing proper play of your job means taking all of your abilities into consideration and learning how to use them. Practice stance dancing, when to heal, and when to chip in some damage.
