I am a 1000 ELO player on 1v1 (17,000 ranking in the world) and when I play team games I play with my friend who is much better, 3000 ranking in the world (around 1400 ELO).
Our team game ranking is around 10,000 in the world which works mostly as he usually carries our team, even though our team game rankings and elo ratings are very similar. Because we are playing with people around the 10,000th best in the world he is better and I am worse so it balances.
But when I play on my own, my team and I usually get crushed, because DE thinks I am much better than I am because I normally play with my friend who is much better than me and so I have this “inflated” rating. Likewise, when he plays on his own he normally wins, and so it is not so fun. What’s worse is when I play with other friends who are very new to the game and don’t play so often and are much worse than me DE assumes I am very good because of my “inflated” 10,000 in the world ranking, and so we always get stomped on.
Also Team Game rankings seem very unreliable, my TG ELO is 800 higher than my 1v1, but sometimes I see people who are much better than me at 1v1 with TG ELOs the same as their 1v1 ELO.
So, I think it would make sense to factor in the 1v1 rating as well as the TG rating, because the 1v1 rating is so much more accurate to how good a player is. I hear chat on streams saying that they’re 1300 1v1 and 2200 TG and stopped because they play against people like Slam and it’s not balanced even though according to the TG ratings it is balanced.
Taking into account 1v1 as well as the team game rating would undoubtedly help, and maybe my friends who are much worse will come back to play with me. And maybe I would occasionally play team games on my own because I won’t always get stomped. For players who don’t have a 1v1 rating, then I understand just only using their TG rating in the matchmaking equation makes sense.
tl;dr - DE thinks I’m a top player because 80-90% of the time i play together with my high rated friend, so whenever I play on my own, or even with my newbie friends we always get stomped and so have stopped playing. TG rating is very inaccurate.
