Just like digsites it would be great to just have a list of all available arenas to be able to select one. Even better would be showing this list with the "Update All" function being able to pick one from there. Would be a great alternative to usual QMs.

That would be nice. I should definitely list the template, and preferably the rewards as well.

And it would be very cool if Fizzer fixed that bug where you get the awards from the wrong arena!
(Or maybe he already fixed it, I gave up playing arenas after that bug...)
