Use the stealth exospine to easily back stab the wanderers. Then only those freakin robots will left. Still they are extremely annoying to fight in pairs. But yes, that's a nice spot.
On the 2nd group of enemies do the triangle charge, then l1 o twice to flip the Droid. Then kill the turrent Droid. Then kill old Droid last. I have a expanded cheese route that is pretty good lol
