Remove shredders

They are nothing but annoying. Add absolutely nothing to the experience, have excessively much HP (takes too long to kill even if easy), their tracking makes no sense as once they lock onto you they will track you and noone else, even if someones right in front of them. Some places on the map like medical research make it outright impossible to res your teammate because you have to run very far to lock the shredder in a room unless you have a barricade. They also stay in 1 place way too long. They either need to be made less annoying or removed altogether.
