Well, TF2 doesn't seem like a disorienting game per se, but the generally fast pace of the game can and probably will add to the disorientation.
Personally I wouldn't call it addictive either. But from the sample of people I have around me, I'd say that games with instanced gameplay tend to take up a lot more time than expected, especially if the next round is loaded automatically. It's what I like to call the "One more level" problem. Every round is relatively short, but the number of rounds has a slight tendency to get out of hand.
An exercise:
Name something that you do not do but should/wish you did/are told you ought, or that you do less than is normally recommended. (For instance, "exercise" or "eat vegetables".)
Make an exhaustive list of your sufficient conditions for avoiding this thing. (If you suspect that your list may be non-exhaustive, mention that in your comment.)
Precommit that: If someone comes up with a way to do the thing which doesn't have any of your listed problems, you will at least try it. It counts if you come up with this response yourself upon making your list.
(Based on: Is That Your True Rejection?)
Edit to add: Kindly stick to the spirit of the exercise; if you have no advice in line with the exercise, this is not the place to offer it. Do not drift into confrontational or abusive demands that people adjust their restrictions to suit your cached suggestion, and do not offer unsolicited other-optimizing.
