First, the problem is not my internet. I played the game for 2 weeks with no issues at all. Last night the game froze during a zone change loading screen and since then Ive had a plethora of issues with the game not loading at all, or I load in after 5 minutes and have extreme lag, or i load in fine and play for a cpl hours until a random zone change starts the lag again. I would really like to solve this, but ive tried 3-4 things advised to me from other players with no help.
