I don't have issues with disconnects. Out of curiosity, did it happen at random times, or during a specific event, like a flashpoint or something? I kept crashing in Esseles during the FTL cutscene. It's a known bug, apparently.
Best thing about BioWare's SWTOR development team is that they don't seem to clean up the code when they make changes. Every patch, some old bug resurfaces.
