if a 2 players one in we will say gold 5 and the other in silver 3 or 4 play together what elo
so higher elo or lower elo like will it be gold elo or silver elo
so higher elo or lower elo like will it be gold elo or silver elo
I believe it's the higher persons elo but I could be wrong.
If you're asking what mmr you'll be matchmade against if you're in a premade as a gold 5+silver 4, it's against another duo with around the same average mmr (so silver 2 ish, if the gold 5 has gold 5 mmr and the silver 4 has silver 4 mmr). If matchmaking can't find another duo with a similar average mmr, you'll face randoms with a slightly higher mmr than the average of your mmrs in order to compensate for the extra coordination you have as a duo.
It's important to note that it's all mmr based though, actual ranks don't matter (other than if you can duo with them at all in ranked).
