Are you all on PC or Mac?
Have you tried flushing DNS or other networking trouble shooting?
I would suggest trying a new DNS as well, most ISP ones suck and are less secure and spy on you and block stuff anyway.
I just started a Necro, I can definitely seeing it being far more viable with Kinetics.
I'm doing Ice with a friend who is running a bubble Defender, pretty great so far as a duo.
