I don't think the issue is whether WoE takes up too much time in one day. 10 minutes to 40, depending on your paranoia & nooibishness level, isn't too much to ask.
However, it presumes that logging in on a daily basis is the normal and anyone else is slow. People who have to skip the occasional day can feel like they're letting their teams down. I'd rather people had 48 hours in which to live their lives, do their stuff, play their real game (Elements), and then squeeze in a bit of time for this sub-game on a forum.
