I believe ARR deserves high sevens to low eights, so it's not too far off what I would give it, personally.

But put yourself in the shoes of someone who has had this game a week, plays casually (2 hours or so a night) in NA prime time. Chances are, he will either have not been able to log in, or will have spent over an hour spamming enter to do so. Add on to that the problems in the opening weekend with Duty finder being broken, constant maintenances etc. What score do you expect him to give. Games are typically reviewed at launch. Asking for this one particular game to be given some kind of special allowance for teething issues is disingenuous.
