The last time I offered a 1000 palladium wager it wasn't accepted :/
The problem is that SJA can just spawn the ships she wants to fight. In order for us to find that specific scenario of 2 elite vultures, we could spend an entire day and come up blank. So what wager did you have in mind?
Besides, reverse flying doesn't work against _multiple_ ships now as it is. Two vultures with fixed lasers can brute force any large ship in the game. I am talking about a 1vs1 fight, in which flying reverse right now offsets any maneuverability advantage in favor of the heavier ship. A single vulture may be able to overtake an Anaconda temporarily with boosting, but only for a moment. Against a python it's already pointless, as the Python in reverse is not that much slower than a boosting vulture.
So yes, I'm fairly certain that multiple Elite ships will be a threat (or already are now), even if you FA reverse off, but that's not because they figured out how to beat FA reverse, but because the odds in this game massively favor the side with greater numbers.
