Solo grind ! Vs duo

Why is solo grinding way harder then duo ??? Like it’s much harder in my opinion

In theory, by duoing you are cutting out 1 variable.

People tend to work better with someone they know that 5 random.

In a 2-stack, the matchmaker will try to group you with other 2-3 stacks against other multistacks. In solo queue you will most likely get matched with and against other solo queuers.

If you are playing with a friend, you probably take OW a bit more serious than the average player, the same is true for all multi-stacks.

A lot of solo players just want to do their thing, they want to play Widow, or Genji, and might not care about teamplay that much.
