Hello,
Unfortunately, it is unlikely that this level of reworking will be done to this system of the game, as this would require a considerable expenditure of man hours and resources and would be expensive to implement. I can, however, provide you with a few workarounds to the system to make your gameplay better.

1) If you are constantly coming up against a player that is retreating and are tired of them retreating and just want them gone...retreat first. Chances are good that they are trying to finish missions and aren't having luck. If you retreat and give them wins, they will go away.

2) Change your team. Training arena matches based upon the same point system you see in Zenith. Each ninja has a point value assigned to it. When you click "training battle" in arena, it will attempt to match you to someone with an identical team in terms of points. If someone is found, you will get an instant match. If not, matching will take longer. If you are finding an instant match, and dislike who you are matching with, change your team so you have a different point value.

3) Change the length of your queue time. Similar to above, if you find yourself matching someone you dislike often, refresh your queue often so you do not match against that person.

Unfortunately, Arena is a dynamic player versus player environment, so no one can fully control the setting. This means that sometimes we will come across scenarios that are not fully to our liking, and there is just nothing we can do about that. No system is perfect, and no amount of rewriting the system will ever fully address that. Even with the proposed system there will always be flaws. For example, players that want to fight their friends might complain about being locked out of fighting their friends for 12 hours in the proposed system, etc.

I hope these suggestions help, please feel free to post again if you have any questions or any more suggestions!

>>>1: that is not my experience at all, I too have farmed moon scrolls fairly recently, and I have come up against meta teams, mods, and the richest of the rich just as >>>often when using my basically forgotten character- sound 4, konoha 9, pains etc
It's possible you're coming up against these teams after the gating process has run through enough time to relegate you to the "match against any team" process, since it couldn't match you to a relevant opponent.

>>> - if you do match with friends the chances of that are atomically small, the chances of matching a friend 3 times in one day are less likely than me becoming CEO >>> of oasis

And I know plenty of people that don't like doing arena, so they match with their friends to finish arena missions. And they can do so reliably and quickly all day long using the rules I described above. They have no issues whatsoever doing so. They do so far more than three times, and none of them are CEO. They can so dozens of times, and can quickly complete all of their arena missions and even their first time arena mission designations for moon coins. Perhaps you didn't read what I outlined clearly enough and missed a step?

>>> 2: even if that is true, that is still a bad way to handle it, that means if someone gets lucky or if someone spends time saving coupons to go for a rare character they >>>like the current algorithm lumps them in with whales just for being in possession of an event character?
It actually isn't about being an event character. I personally like to use New Year Hashirama in arena because I find him quite fun, but I find myself matched against Team 7s quite frequently, as his point value is quite low, much to my chagrin, as I often find myself obligated to give such new players free wins. NY Hashirama is valued fairly low in terms of total points, despite being an event ninja. Event ninja status is not the determiner of point value.

>>> levels are equalized in arena but outside stats still matters because you know someone who was able to buy and 4 star shisui susano is going to have enough init to render any player who won shisui in wheel useless. It means that "training" is still not viable as a means of training because someone who won or saved enough coupons just to recruit a character still going to be obliterated by a whale who was able to drop enough coupons/ingots to get them, maybe 4 star them and the inevitable power items that come with it . I do not know if your post implies that star level is taken into account, but I can assure you that my 3 star ronin team is not on equal footing to the 4 star madara jinchu, 4 star kimi halloween, cancer tsunade teams I face ad nauseum.

Strategy and cleverness is also important in arena. Again, personally, With my random collection of non-meta ninjas I've yet to face a tsunade/ten-tails madara "meta" team I can't beat. I understand that you're feeling discouraged about this, but a full rewrite on this system is not something that is going to happen. Graduate teams of computer scientists do not grow on trees. And, again, and system you are proposing will be just as full of flaws and holes that others will hate as the system you hate now.

>>> I am bad with words I know, so just to be clear, I know this is not something in your power so nothing against you and you probably will have a script to go off given >>>how strict the censorship is in these forums, but none of what you said actually applies to my suggestions, I ofcourse have no power here, but the suggestion
>>> remains valid, a simple tweak to the training arena matching algorithm would be an easy enough implementation and would allow us to use training arena to train
As it is now, the training arena exists to practice using lineups, and it does just that. It is not perfect for that, but no system is. Ultimately, I *can* submit the suggestion you're proposing, but because of the large cost inherent to the proposal in both man hours and resources, I can't promise you'll see a return. Also, since you're the only person advocating this system, and it has no other support, it's not likely it will get much momentum. It's far more likely that others will dislike your new system than that others will dislike the current system, if that makes sense. At present, I can mostly just suggest "changes" and "improvements" to the current arena system, something all players definitely want, but there doesn't seem to be much interest in your current, proposed system.
