Hello,
Ranked arena is a fair game mode, or at least a fairer game mode. Most power considerations are removed.
I will submit your suggestion for you again. For the meantime, I would recommend visiting the strategy section of this forum or the official discord for tips on how to do better in arena. You said that there is no strategy to the game mode, but there is quite a bit, so those two places may be able to help you considerable.
Thanks and have a great day!


Edit: As I'm filling out this report, I noted you put "remove wait times". This isn't really something that can be done. Wait times are dependent upon player involvement. We do not directly influence that. That is up to the players in your region. If you have some alternative suggestions in place of this one you would like me to submit, I can hold off on submitting this report until you get back to me.
Also, can you elaborate on what you mean by "match restrictions"? Did you want anyone to be able to fight you, even if you are on a lose streak and they are on a win streak? That's really one of the only restrictions in this game mode. The other is that high ranked players have a harder time matching with low ranked players. Are you sure you want these removed?
