Ya I imagine I'll still find a few cool hiding spots that aren't soft walled but I don't think I'll be joining HLG.
You can back up and hide at LOTS of places on that map (and other maps as well) to let your shields recharge (it's not unfair) - like that big hill in the center of the map, or any other rock on the map. Besides, if someone was shooting you from a banshee or from the side (like where the cave is) they could easily kill you while you're wide open, without cover, on the open surface of the cliff - like I said before, it's a nice vantage point but being on top of it doesn't make you invincible. There has to be another reason, right?
