Can’t create a poll, but feel free to write down your opinion.
I think it is not necessary, but could be a great addition (especially for new players, who can’t play ranked yet).
On the other hand making it the default playing option -practically forcing it- could do more harm than good, if there are some flaws in the matchmaking algorithm, and filling up the place of leaving players, etc.
For example in Paladins if you party up as a full team you get way stronger opponents. And by way stronger I mean that they have 35-50% higher MMR, so you better not play in a 4-5 party unless you like getting stomped, or you are so good that there aren’t better players.
