Seriously… who’s brilliant idea was this?
Why on earth would you ever change the friendly fire to only damage the vehicle. In at least Big Team slayer you can fully engage and destroy a friendly occupied vehicle with out doing any actual damage the allied pilot. This allows any -Yoink!- to kill your tank/banshee/gaus hog/ any -Yoinking!- vehicle because they were not able to get to it first, without any danger of being booted.
Outrageously -Yoinking!- stupid.
