To accuratly paraphrase Mr. Brooks' many contributions to all of you that are having stability issues with SWTOR:
' Bioware servers are the greatest ,most robust, servers on the planet. Any stability issues you are having with connectivity is YOUR problem. The fact you can play other MMO's without major issues. like those found while playing SWTOR, is only a figment of your wild imagination. '
