If I were to start BB, I think I would have started else where than a another starter box. Why not get a team you really want, instead of the random 2 new ones?
I think you could say similar about any starter set. And I have often wished the traditional two faction boxes were replaced with a permanent special offer, letting one buy rules plus two faction boxes for a special price. But the BB starter seems fair value, even if you don't want the teams.
You get rules, pitch, tokens, and dice, which would probably cost about as much anyway. And if you really don't want the teams, you can always sell them - could get half your money back that way.
