Onesy,
Bfa IS included in plunder outcome.
What you worked for hasn't been taken away. It will be temporarily disabled in the system's eyes for 1 hour. These wars are tests, it's not like they're switching it up mid-season. They see there is a problem and they're testing different ways to fix it.
Your bfa still works the same outside the war, and it will still generate you gold(when hired). So don't complain, be happy that they're working on leveling the playing field.
This is a good change, not a bad one.
