This game is not competitive because bioware never made anything worth competing for. There are no rewards or "ego stroking" that would be needed for competitive ranked teams. Simple things like unique titles, special armor sets, something/anything for the top % of pvpers and pveers. In turn many of the good pvp guilds and pve guilds have left this game for other things.
Try telling that to some of the top players. "Zomg my rank will go down!"
Whoops, did I just use logic?
Now, if it weren't pre-season and there were something to aim for -- I'd definitely agree with people, but as it stands there is absolutely no point of a rank at this point other than being "good" in pre-season (which obviously people get off to, somehow.)
