I don't think you guys really understand the point of "ranked" servers. The only way ranking works is if everyone is playing the same game - that's why in MW2, they disallowed private servers, because that was the only way they could ensure it. They've opened it back up to private servers, but...you guys are really abusing that. How hard do you think it would be to write something so that they could block a specific perk on your server? That would take Treyarch like...30 seconds. They SPECIFICALLY didn't include it because it's not meant for that. Having pre-teen admins babysit your servers to make sure no one's using second chance is a pretty dumb way around that.
Football teams are ranked also - this is possible because they're all playing the same game with the same rules, the rules don't depend on who's field you're on.
It's a stupid restriction anyway, because:
1) Anyone using second chance is obviously not very good anyway, so it's not like they're gaining much
2) Anyone dumb enough to shoot someone, and:
-A) Not notice the score for killing them didn't flash
-B ) Not notice they're still moving
-C) Stand there for 10 seconds while the second chancer unloads their whole pistol into them (that's about much it takes) and not know what's going on
deserves to be second chance killed.
All you're doing is annoying EVERYONE on your server, when there are no admins the impossible-to-enforce (without an admin) rules still flash from Console, and when there ARE admins they constantly repeat and repeat that there's no second chance, and then kick people who mostly don't understand what they're talking about. If there was an admin mod or something from Treyarch that just disallowed it then it'd be whatever, but from playing on your servers, let me tell you, the focus is NOT on the game and letting people play, it's on enforcing that stupid rule on everyone.
