Well, it's tournament season. Origin's tournament is coming up very soon, Gencon is after that, etc. The people who are participating aren't likely to share their strategies for everyone to see. That might be part of the reason why.
Another thing might be that with (relatively) so few Mages, we've discussed so much about strategies. There are only so many viable strategies you can have with a Mage.
When FiF comes out, expect there to be a surge in talks about this topic though.
