There is no method for boosting rank with just two people. It just counts for one win, no matter how many times You play/boost. Thats why i offer My help. Hit Me up on live and ill get back to You ASAP. Sometimes My rank resets which makes It impossible To help but It happened twice now And after a week or so i had My rank 5 back. Keep trying guys. Hit Me up anytime to give it a Go. Hope This helps
Edit: Now the game is free i have tried multiple friends to help with this cheevo but it seems impossible to get matched together. I will still try help You guys but best around noon gmt. Then its most calm online. It will get easier after the first couple weeks its out I hope.
Edit 2 : 18/6/2015
Since My rank tot reset To lvl1 I am affraid I cant help anymore. Not sure If It's just me who got reset or if more people got reset
Edit 3 : 12/9/2015
My rank is back on lvl 3. They must have fixed It because i helped a friend earlier today and it works again so If You need help for This cheevo and You are lvl1 or lvl2, i can help again. Add Me on live or Message Me on live and I Will help You. It's also really dead online now since It's been free for a while now
Edit 4 : Due to the game being free and the Massive amount of requests i cant help anymore. It's taking up too much of my time. I will leave the solution up here as for people who look for a boosting buddy it can still be usefull. My apologies for not helping anymore but the last few people I helped, it took Us over an hour to just get the normal win to count and since I'm still rank 1 after being reset 3 times I still would not be able to help get this cheevo. For people still going for this, I wish You good luck and if You are rank 2 or higher and willing to help others with this cheevo, please post your gt in the comments. Thank's a lot for all the feedback everyone 🙏👊
