While I'm sure they'll add more melee features in the next expansion (cause to be honest even being primarily caster right now, the melee is still a little dull) I think they're still going to keep it a primary caster. Not sure when but they even warned people ahead of time that it's even going to be a caster first and focus on spells. I personally don't think their going to move away from that in the future though i do think they should still add a bit more to the melee aspect of it.

As far as boring goes, that's entirely subjective and sounds like it's just not the class for you. While I personally agree that to me it's a rather boring job to play just based on how I enjoy playing the game, there are plenty of people who have fun with it and prefer it's simplicity.
