Ubisoft is taking a new approach to deal with Rainbow Six Siege's teamkilling problem. In a new blog post, Ubi detailed the new rules going into testing. Instead of kicking players after two teamkills, all damage dealt to the offender after the first teamkill will be reversed onto them. If the teamkill was truly an accident, the victim is able to "forgive" and not activate a penalty.

"The goal of this system is to contain the impact of players abusing the friendly fire mechanic, while maintaining a degree of flexibility for accidents," reads the post. When the reverse damage mechanic was first tested in the last test server, some players worried it was too harsh a punishment for a truly accidental teamkill. The piece of the puzzle that seemed to be missing was the forgive option. Players have been asking for a forgive option for years, but Ubi has been strangely silent on the subject until recently.
