1. Create a High flyer or 5. Do not get attached to them.
2. Load into the battle ground challenges and check to see if they have some nice cash prizes like in the picture and if they do not then delete them and remake them until they do.

I created and put 4 classes all the way through the battle grounds leaving the high flyer for last and maybe luckily so. I learnt on the first 3 fights just how powerful he / she is against say battleground AI.

Ok so the move you need here is the spring board and the best part is it cost neither stamina or heat. To do the spring board you run towards the ropes and press kick. Depending on distance or if the opponent is laying down this will give you one of three spring board moves. You will not believe how much health this will take on a single blow if you hit them. If they are standing they will be knocked out cold for you to just run back to the rope to repeat the move while they are on the ground. If you are on pc and use a controller you can also use the keyboard keys Q and E for submissions.

That really is it but things can go wrong here and there but on a nice run a 64 overall rated custom character is able to take the rock down under a minute easy. Characters that parry the springboard on the ground can be a hastle just like being thrown to a crocodile early or the opponent running for the ram. Just restart the match and try and get the first few springboards in.

Holding the Left trigger and pressing down on the right stick will do a stunning kick which you can get in early and is pretty much a free springboard attack because they are left stunned while standing.

1. Fight towards the money.
2. Fight towards the money.
3. Fight towards the money... Like in the picture.

Try that out. 3 days of farming after figuring it out I managed 520k. Delete the characters you earn all the cash prizes for and remake them until you get one with a nice challenge tree with nice money.

Oh also you can probably pin at around when you see 1/4 left of the yellow bar and the rest red on their health if you mash the buttons fast enough. You may also end fights in around 10 - 15 seconds without your finisher on some of those lower fights.

Feels extremely overpowered and it is. Let us hope it stays that way so you can save some time and or money.

Overall if you still want to farm 6k an hour doing exhibition one vs one battles use the high flyers and you will get more anyway but you will get MUCH more through new character trees in battle grounds.
