Is SWOR less buggy if subscribing?

Hello,

   I have played "Star Wars: The Old Republic" for little stretches of time over the years. While I do enjoy playing it, I lose interest because I run into so many bugs over the course of playing, such as sections of the graphics missing entirely (say, a computer I need to interact with or some aspect of the environment), or issues with freezing (No, I do not have a PC incapable of rendering this game smoothly), that I decide to leave the game alone for a time. I then play again several months to a year later to see if the game's quality has improved. I am about to embark on yet another try, though I have been let down so many times.

   Thus, my question to subscribers and the developers is: "Is the quality of SWOR better if I subscribe?" The reason I have never subscribed is that I have been waiting for the quality to improve, yet this never seems to happen. I am beginning to wonder if some of the issues I have experienced are due to overloaded servers, and the possibility thus occurred to me that, perhaps, the subscribers access different servers that run more smoothly. Hence, if this is the case, I would likely subscribe.

   If there is a developer in this forum, please enlighten me on this; I would be much appreciative.

Thank you,

Michael
