In all honesty, I have not even tried M&F yet. I simply didn't have the time lately to play another game and real-time aspect would be discouraging for me as well. I actually do put in a lot of time in BM, when I can. But I also love the option of logging in quickly on my phone for like 5 mins for a few days in a row, if I hardly have time. So I would share that concern definately as well.
Other than that, I'm afraid I'll have to disappoint you for the next few weeks, but maybe after that I'll give it a try just to see.
