Yeah, I'm pretty sure I spectated a game last year with you playing USF vs OKW with the OKW player doing exactly that, and I'm pretty sure you're not rank 1000.
My sole point was this: Once you reach the higher ranks in 1v1 and 2v2 people will know how to counter a forward battlegroup. At that point, not only does it cease to be effective, but it becomes detrimental for you. That's why I just don't feel it's a valid strategy.
