TNA iMPACT!

Just to confirm a couple of points, and sometips:

This achievement is easier if you do not have any losses, as this counts against you. It must be in ranked online play, but can obviously be boosted with either a helpful friend or dummy account. At the time of writing, you should be able to achieve Champion status on the Submission leaderboard at about 60 wins. You also need to view your position on the leaderboards, making sure to select the correct leaderboard as different match types have separate leaderboards and champions.

The quickest way is to select the 'Mexico' arena and 'Submission' match type, and select AJ Styles. Walk to your opponent and hit LB + A to hit an Insiguri kick and lay your opponent down. Walk around and stand behind the head of your opponent and repeatedly hit Y to fire elbows on top of his skull. Seven or eight hits later, the head part of your opponents health picture should be dark red, so hit LB + B to lock in that submission and hit three x three button sequences to finish the match. This can be as quick as 15 seconds, but with matchmaking and loading takes approx 2 minutes per game.

Edited to add: Having finally finished boosting this (Thanks DivineWind72!) the ranking (with wins I needed to achieve) goes:
Jobber
Rookie
Journeyman (55 wins)
Mid-Carder
Up & Comer (56 wins)
Superstar (57 wins)
Main Eventer (58 wins)
TNA Champion (59 wins)

In order to get this achievement you will need to become a TNA Champion on the Live Leaderboards. At first this may sound daunting but it is doable. It will be a lot easier if follow this method.

1) Arrange to meet a friend online and get them to set up a RANKED Submission match.

2) Now you need to select QUICK PLAY and hope you match up with your friend. Nowadays its easy as their aren't that many people playing online.

3) Now you defeat your friend via SUBMISSION and repeat the process 40 - 50 times.

In order to unlock the achievement you will need to keep checking the leaderboards as it won't appear until you see your name at the top.

Ok this achievement is screwy. My friend and I did this and it took him 70 wins (in a row that is), and me 73 or so. We had started by going back and forth with the wins but that doesn't work. You need one person to win continuously. We were both "jobbers" until around 51-57 wins. So basically your going to be a "jobber" rank for a long time, but once you level up you fly through the other ranks really fast. So just keep having your boosting partner win until he gets it. If you have losses already it will take you longer to get the "TNA Champion" rank. So just remember that. Any questions or comments let me know.
