it's a question of difficulty
it was really difficult without world-class skills to block a pre-errata phantom because it had to be treated as 3 separate ships that had to be blocked simultaneously or it'd just race round the swarm without consequence. Errata now forces whisper and the like to think ahead, reducing the ease with which she dance around most everything.
the other difficulty is luck and M.O.V against turrets. You can't fully outplay a turret, even blocking it produces slight benefits compared to normal ships (unless you block it atop a space peanut) and they're worth nothing unless they're 100% dead. If they get lucky and start dropping ties, your chances of winning decrease significantly.
A great swarm player might be able to bulldoze through those, but then you have to account for all the other players that the turrets just gobble M.O.V from. I've seen many many games go 200-0 where it looked like a complete rout, but in reality it was just one or two bad throws that left a decimator/falcon/phantom at incredibly low health, just not enough to count for jack ****.
