So I got back into d2 in season 11 and have been playing ever since. In season 12 my connection in 6s was fine but the after that I started having nothing but lag in them. I don't bother playing them including iron banner because I lag so bad. The same goes for the tower I do nothing but lag I would like to fix this issue before witch queen. I know its not my connection because I can be the only device on in the house at 15mbs. Im on ps5 if that makes a difference. I don't lag in 3s or raids so I don't know if its because my hosts are all in Asia when I'm in Ohio or what.
