Solves nothing, you’ll just get 4 healers and a FC. You’ll still get stomped.
There is no way to make a solo queue work, Destiny 2 tried this and you know what the solo queue times are? Nonexistent. The game simply don’t pop because solo queue doesn’t work.
There is no way to make solo queue options work in battlegrounds without increasing queue times to untenable levels. Just look at solo shuffle in retail. Imagine that but for every single BG you ever queue up for.
The vast majority of people simply say forget this and go to the insta-pop normal queue, the people who stick it out aren’t enough of a population to get games started. Its a waste of time and dev effort to try to implement it.
