You mention several "issues" but you're only linking to hack threads. Are they such a big deal for you? Personally I'd say that 99,9 % of all hacks hail from people having no idea what other classes are capable of, bugs and/or network issues. The latter would explain why some people suffer more than others, get a better connection. The remaining 0,1 % could be made up by 0,09% intended network fiddling and 0,01% code.
All we have so far are videos in which one person may or may not have been up to something. You rarely to never come across a video in which you with certainty can say that a person was hacking. And yet its such a big issue. I take 6,9K hits in 1396 expertise on a game to game basis, I think that's a bigger issue.
Second this, also the lag spikes since friday. I don't think there is not hacking going on, I think you ahve to accept that in all games there is some hacking of some kind there (to what degree I don't know) but a lot of what I see could be accounted to not knowing the other class, and Lag issues (there are a lot of lag issues in this game). The engine seems to be far from stable at times. I just completed a new rig for the upcomming ESO beta, and launch. Along with this build I included software to moniter incomming and outgoing connections on my ROG MB. Normaly I see two connections to SWTOR, but during the lag spikes (when I have everything else locked down) I had three pages of connections running on ports that SWTOR is useing. there are bigger issues in this game than what people think are hacks.
