So I think this is a good point, definitely worth considering when looking at any request (how it affects different people and to what degree), and I’d probably agree with your analysis here, tbh, even as a non-Arena player.
I think the desired functionality, though, was an unobtrusive “Back” (
) button available even during the Troop selection process (i.e. where I assume the next time you enter Arena after exiting, the fee would have already been paid, any Troops selected would remain so, and you could continue selecting from where you left off). This wouldn’t negatively affect any enthusiastic Arena player, I don’t think (and occasionally even help).
I agree that it’s a small thing in the grand scale, but I also agree that it would save that small frustration of having to try pick four troops for your next run when you just want to do something else. I have no idea how much effort the request would require on the devs side, so can’t really make a comment there.
Another add-on to complement this could be a quick “Refresh choices” button (
) that lets you repay 1000 Gold and get another four choices without additional prompts, unlike:
Another option as an alternative to the much requested ability to see all four selections at once (12 Troops) could be to have a “Re-select Troops” button (
) (I’m obvs just making these up, could definitely be better image options – I was imagining a single counter-clockwise arrow, but w/e). 250 Gold ¯_(ツ)_/¯.
