Titan on the surface seems pretty straightforward, and even in some cases a little bland, but then as you continue through the story you enter a large dome like structure that is rich with interesting locations. But, there's no reason to venture there outside of story/strike missions, which seems like a huge waste. The arboretum, solarium etc. should have been an active patrol area with public events, chests etc. I love exploring the area and it's a shame that there's not really anything else there. The patrol area on titan makes it feel so small and insignificant when in reality Titan has a huge playable space with some of the most interesting looking areas in the game! Bungie PLEASE expand patrol to these areas on Titan! It would open it up so much more and make Titan feel so much bigger!
