Can solo players be put against pre-made groups in standard?

I’m beginning to realise that Standard mode might not be the most balanced. A lot of the games I’ve played are against highly coordinated teams, which makes me wonder if they’re pre-made groups.

If that’s true, then statistically the odds of a solo player winning are very low.

Imagine there’s a pre-made group of five experienced players queuing standard together. Standard is the only way for large groups to play together, so there are likely many groups doing just this.

In any match they are in, this group will almost certainly dominate. They may well have planned specific characters and a strategy, along with having the benefit of actually knowing each other.

If you are a solo player, the odds of you being the 6th member of their team in a match are very low. You’re far more likely to be on the opposing team which is almost guaranteed to lose.

At the same time, there are brand new players trying out characters they barely know. The only way to guarantee you won’t be on the same team as them is to be in a pre-made group, which in turn means solo players are more likely to get unlucky.

Even if you are playing at an Eternus level, how realistic would it even be to have above a 50% winrate in Standard without a pre-made group? Are the odds even in your favour at that point?
