It's because when with friend, it also places you against premades of the same or similar caliber, so if you're with 3 ppl, you're placed against the same amount, which means unless you are as serious as the other premade, they'll steamroll you lol.
the system actually punishes you for doing the very thing they want you to do, i.e playing with friends
if you duo you get 3 people who are eating paste, vs 5 normal functioning players
if you trio this seems to have the best effect if your trio is solid but the duo you get can often be eating paste
and 5 man is really up to you, if you have weak links, and you know you do, you're losing.
