With the rate that MLS is expanding I predict that there will be never been a balanced schedule. I would rather see the whole we play during FIFA breaks thing corrected before a balanced schedule.
This is getting off topic, but I agree that we aren't going to see a balanced schedule. Still, I would like to see a longer season. The Premier League goes for 9 months plus 1 week - 42 weeks to play 38 games. We go for 34 weeks to play 34 games, plus another 6 weeks for the playoffs. One thing people don't focus on with our playoff system is that it robs us of regular season games. Still, even with the playoffs our season is 2 weeks shorter than the Premier League. I'd like it if we could start a month or more earlier. Begin the season 6 weeks earlier in late January. Play more games in the south and the Pacific coast. Then, make that up with more games in snowier locales in the summer. Play 36 games in 39 weeks. Then have the 6 week playoffs end with the MLS Cup on Thanksgiving weekend.
