At least Greavers have a predictable flight pattern, coming right for you in a steady straight motion before trying to get to your backside so they can bite you on the butt.
But these (relatively) new Gorgos jump around randomly like a hyperactive bag of potatoes with a deceptively deadly range. Geez, they're annoying.
Iunno, i still seem to have more problems with greavers than gorgos, keep a good distance from them and you´re fine, be patient, and bring piercing (preferably a gun), however greavers still outright murder me without a second thought, especially if theres more than one
