I've had a really good time with it so far, and after a handful of hours I have almost all of the rewards.

That said, it seems like it will be a significantly longer grind if you're less skilled at what these mini-games are asking of you, especially since the biggest bottleneck is the queue times. So if you lose right away, enjoy your 50 currency, time to wait another 5 minutes.

I think the other unfortunate downside of the game is that it can seem really hopeless if you're bad at it. I've already met numerous people (both friends and acquaintances) who seem to have given up; they queue and then AFK and await their loss and 50 currency.

And I get why they do that; this isn't a PvE experience that has been tuned so that players have the advantage, but rather a PvE experience where the skill level of other players determines the difficulty level. And if you fall down enough and don't feel like you're making any progress with repeated efforts, it's human nature to eventually learn that further efforts would be fruitless.

While I don't expect to see any changes, from a design perspective I wonder what kinds of adjustments could be made to the experience to mitigate that feeling of hopelessness for this specific subset of players? It'll be interesting to see if things change over time, like if the difficult level decreases as skilled players finish getting their rewards and stop queuing, etc.
