Too many overseers in Corkus Grind Spot

Previously, There were overseers but the quantity has become ridiculous. I cannot grind for more than a minute before I 1) get dangerously close to dying and need to leave the area or 2) die. Why does there need to be so many? In one spot there were at least 4. Probably 5 times that amount in the grind area. I just want to level up and the T-12 overseers are making it extremely difficult
