Yeah, you do need to cater to the groups skill level. It's part of the group play dynamic. This is not an advanced concept. If pushing them past their limits causes wipes, it's only going to waste more time. That's the only retribution you're going to see, wasting more of your own time by not cooperating because you're better. If you don't like this, don't consent to be matched with anyone of any skill level by using roulette. Roulette is not and never has been the "Match me with players of equal skill button". The only ones causing problems is the ones bullying randoms for not meeting their standards that belong in a premade.
