I hope they make it like Marvel Avengers Alliance 2 where you don't lose rank when others play the AI version of your team, but only when you actually lose when trying to climb up. I didn't play MAA1, but I heard that was a beast -a total grindfest that included chunks of hours the last few days of the tournament and lots of gold.

Bottom line: I'm looking forward to it, but I won't be thrilled (and perhaps won't participate fully) if it requires lots of grinding to get anywhere.
