Has it always been on? It's basically impossible to not kill team mates a few times, and I just lost a pretty good game because one of my team mates killed me when I was the last defender back and he sent the ball carrier the rest of the way to the goal.
Propelling the carrier with your teams hammers has always been part of the game though
it's not like sending the non-ball carriers flying would help you any
Yeah but doing it with just the right amount of space to not kill the ball carrier took a bit of skill and sometimes luck. With friendly fire off the game would just be constant launching of your team member to get him to score instead of actual dogging and planning.
It'd be like football with only hailmary plays every down.
