Is there a way to make your base appear to be an outdoor area? Ways to hide/remove the walls?

Thanks for the ideas, after reading page after page of sentinel posts I settled on water/bio. Good mix of heals,control and AoE damage

I am an old player returning to the game and could use some help. I read through the classes that were not around when I first played and the sentinel looks interesting. What would be a good primary/secondary combo for mostly solo missions and leveling, but would not suck too bad if I did group up?
