I had bad connection to The Bastion over the entire weekend, jumping from 400-1200ms all the time. The only time it stabilised was after Sunday 7pm (GMT +8), where it fell back to what I've been getting pre-f2p (200ms).
There problems this game has shouldn't have happened at all. Bottom line they were given 200 million dollars they bought the rights to a broken engine before it was even ready for release. Star Wars The Old Republic is a tale of mismanagement.
