Ok first of all, sorry for my bad English but this "Exploit" is very great, so iam gonna try to explain it.
1. You need Deadly Boss Mods ( It shows whitch arena u will join an which number it has.)
2. You need one team with 2k raiting. On our server it wasnt a problem to find one. We where three ppl an payed 1k Gold.
Now to the Exploit:
-Meet your friends with who u wanna push your raiting ( Try it in the morning, less teams --> better chance)
-The two players who want to be the first have to join the 1500 Team. The other two players the team with the 2000 raiting.
-Both teams have to joine the que at the same moment, so you better voicechat with eachother.
-Now u have to wait that both teams get the same arena. It wont happen emediatly, but u wont loose points while canceling the invitation and leaveing the que.
Me and my friends have done this with a 1650 Team and a 2000 Team, so we startet wirh a 1650 Personal raiting. It tooks us 4 Hours, at the end we have had an 2000 personalraiting and an 2000 teamraiting.
I hope u understand everything. If not, i will try to re-explain it .
