Hello,
To begin with, I really appreciate that you went out of your way to flash out the suggestions you wish to make, and describing them with why you find them beneficial.
I will let our team know about it, thank you for the feedback :)
Concerning Arena, this is just a personal advice, because as much as I am aware of the matching time there, it sometimes helps to stop matching, and try to queue again.
Have a nice day ^^
