I wouldn't mind making all games 40 minutes per side, as in leagues. Though I know real life games in the expanded era were 60 minutes, or 30 per side, that leaves little room for misconnects and slow servers. Expanded is complex. I am not a slow player, yet I have played games where I've used 25-28 minutes on my side. Having to restart my router would have ended the game - and often, the most complex ones are the most interesting.
