Proposition - Role queue when not in 6stack

As seen in other online games , mostly mmorpgs where tanks/dds/heal system exists. when queueing solo you queue for a predefined role type composition.
But when you go in an instance as a full team you can do whatever you like.
I think we can all agree , the default “good” composition is 2 tanks 2dds 2 healers. i understand being able to do a goats type of comp or triple tank or whatever can be fun or efficient at times, but then people who want to run goats can do it in 6stack .

Many think that the role queue can actually help the game a lot. and the community kinda already established the 222 comp standard.
This would allow a LOT of helpfull stuff, like different MMR for each role , like you can queue as a diamond tank or as a plat dd.

Of course dds will have a longer queue time. but that is same in every game . and i’d rather have 5 or 10more minutes waiting rather than 1min wait and end up in a 5dd team in ranked.

What do you guys think of it ? could role queue and fixed default comp design be the next step after LFG ?

Eh. No.

Triple Support and Triple Tank are both common. In many cases, a team consists of 3 tanks and 3 supports.
