Can something please be done about the "matching" that occurs in this game?

and im not talking about the fact that players with sub 300k power lose 15 points for getting beat by staff members with 1.5 mil in bonds but only gain 2 points for beating 2 600k players

im not talking about f2p and new accounts being put up against jin, kagari,liz,loco in matsuri.

All of which are valid suggestions, which have already been made and ofcourse ignored, gotta keep the walking wallets happy, that makes sense.

I am talking about in arena training mode, there are over 1500 servers, even with a lot of them being dead there are still plenty of people online at any one point in time, if 2 people in arena face each other 2-3 times they should stop being matched for a set length of time. Training is the one area in the game we get to try new characters and teams with no risk, but it is made much more difficult than it needs to be because according to the current "matching" algorithm you have in place there are only 2 people online at any given time, today I logged in early morning got the remaining suigetsu frags I needed, tried to try him out in arena, got matched against someone who retreated ( fair enough they were s15*, and using 2 star team 7 ninjas) but they are the only person I got matched against over and over and over again.

Now, I have done some real world stuff, came back to the game 5 hours later and guess what? according to the algorithm still the only 2 people online are me and a person who has no interest in training against me. This is not a one off, this is a daily occurrence, can you set a limit to the number of times 2 people can be matched against each other in training, for example if they get matched 3 times then they should not be matched again for the next 12 hours or so. You could make it more complicated than that and have a system that takes into consideration the number of times people have retreated against each other, but just a simple 3 matches then a break from each other would be easy to implement and would make the last remaining fun part of the game much much better. Thank you
