OvO Rule(s) have been added to the FF 5v5 Rules:
http://ugcleague.com/rules_ff5.cfm#8
8.4. NO chasing: [Red team's offensive players continually chase incoming blue offensive players back into their own base, or turning from their directed path to potshot, or vice versa.]
8.5. NO potshots: [Offense shooting offense as they move past each other. This includes successive potshots killing a single player. It does not include occasional knee jerk reactions to the enemy on a few occasions throughout a match. Do not return fire. If you believe potshots are excessive, then take it up with an administrator. Once potshots are returned, and it appears to the reviewing admin that potshooting has been adopted by both teams, neither team may complain.] This includes successive potshots killing a single player. This also includes anything that would damage an offensive runner of the other team including med kits, crowbars, spy pills, caltrops, demo class pipes, rockets, and grenades of any type. It does not include occasional knee jerk.
SO FROM HERE ON OUT OvO IS ILLEGAL!!
Any match in which you feel there has been excessive OvO should be disputed through the proper channels for review.
Update on the front page as well, make sure your teams are aware of the new addition prior to your match this week to avoid disputes.
