By this point of the latest update, it should be clear that the amount of people competing in 2v2 matches are still minimal compare to season 1 and 2. There should be a different reward chain for 2v2s, the same way there is a ranking system for it, if it makes sense. (Bots are not the answer by the way).
There are many players who actually like to play 2v2s, but due to its minimal incentives, there isn’t many attempts (in arena 50, almost no attempt unless arranged!) in the arenas. It only make sense if there is a plan to “revive” 2v2s, there should be at least the same amount of incentives as there is for single player match. And of course the rankings should be different than 1v1.
Also, I really don’t like the no-incentive gauntlet. As you once mentioned, you could at least put some cool portraits as rewards, and by some, it can be 100, not 2-3 that gets repetitive again after a week or two.
I hope these feedbacks are taken into consideration and addressed for the coming up season.
