OK, I agree partly. I agree when you say that there still should ba a halftime period, but it is simply too long to wait. It often happes to me (and a lot of other players i'm sure), that I stop watching during halftime because it simply takes too long to wait. Why just not shorten the halftime period and make it equal to double the time period between first and second / third and fourth quarter. So 2:30 minutes between quarters, and 5:00 minutes as halftime period.
That way people still have the time to go to the toilet, get food, drinks, ... or something else, like you say AND other people who are just waiting for the game to resume don't have to wait soo long.
5 Minutes seems ideal to me, in that certain people can do what they have to do, and the others who are just waiting only have to wait 5 minutes, so they'll just stay at their computer and won't leave the game during halftime. So everyone's happy !! So maybe something to consider, because 5 minutes will be much more applauded than 15 minutes. Just do a poll and you'll see !
