We've done some playtesting of 2 hit escorts over here. Good thing is - they don't do anything terrible with game mechanics. They're simple to use, and as well might've been in official rules. No problem here.
Bad thing - they're something radically new. Some more conservative players may have problem with it.
But, honestly, those are the same people who'd have problems with BFG R in general. Some of those won't even accept 2010 compendium. So, well, if they passed the vote here, I guess there's nothing to worry about, is it? BFG has left official/unofficial stage years ago, when specialist games site was taken down. Now it belongs to the community. If community wants 2 hit escorts, let there be 2 hit escorts.
