This game wasn't even designed with the 4s meta in mind. It's made weaknesses of certain classes/specs more noticeable and made class balance in general plain bad, so what makes you think SWTOR would be remotely balanced for anything lower than that??

They also hailed 2.4 as "The PvP Patch" and instead of improving and overhauling the ranked 8s system they completely removed them for the 4s system. Virtually all PvP guilds when inactive or unsubbed/quit entirely due to this announcement, especially the top-tier teams who were running 8s consistently.

I think Yolo on Pot5 is still queuing and ruining games for Imps. It's kinda funny actually to see other players take rating so seriously in such a casual driven game.
