Same here, very angry - lag in game is so bad i just cant play.
Please BT fix this

Problems with BT internet and New MMO game - RIFT
In fairness, the first 6 betas had issues with Virgin, so it's not just BT that ahs port and traffic shaping issues.
All i can say is Leave BT there **bleep** get virgin media i can play any online game no lag and if i do have probs with my broadband it is sorted there and then if not i get discount off my bill or 3 months free broadband if it still carrys on
