You're referring, I assume, to the upper river valley starting at Containment and flowing south. It's a huge bowl with lots of overlooks, and is definitely a sniper's paradise. And with one break, you get a repeat of the effect at Cage. These are areas you don't go through. You go around. Valk helps most, but so does Pathfinder or even Wraith. And now, with mobile jump towers, everyone's a Valk.
As soon as you stop thinking of these spaces as your graveyard and start thinking of them as someone else's it gets a lot more fun. Assuming you like mid-to-long range poking.
