It really comes down to how much your own time is worth. You've leveled 8 teams to 80 already so you've proven that you have
some patience to possibly level another team w/o RaF. However, I wouldn't start moving anything over until you see how active
LoB is again in Cataclysm. While I'm sure it will pickup as it does with every new expansion, The Zerg may pick up as well... you
never know.

Oh, and...
