Hello,
right now teamgame elo is absolutely not viable to judge players skill level. it is way to easy for rather weak players to get to 2500 or even a bit higher. and since matchmaking only takes the teamgame elo into consideration when trying to make a balanced game - that should ofcourse be the case but does not work at the moment - a lot of games that on paper have even ratings are absolutely onesided because there are some 2500 players that are actually decent but there are also a lot that are pretty noobish.
but what is the problem: right now the elo a player wins or loses is only done in consideration of the highest elo of the opponents. what that does is making it very easy to win points, but very hard to ever drop significantly in rating.
An easy example:
Team A: 4 Players: A1: 2000 A2: 2000 A3: 2000 A4: 2000 Team elo: 8000, average 2000
Team B: 4 Players: B1: 2800 B2: 1700 B3: 1700 B4: 1700 Team elo: 7900, average 1975
this would propably be a pretty unbalanced TG in the current ladder, since i think that the 2k8 player should be able to carry his team, but i only use this as an rather extrem example to show the current issue.
If Team A wins: A1, A2, A3 and A4 gain 15 elo, B1 loses 15 elo, B2, B3 and B4 lose 5.
If Team A loses: A1, A2 A3 and A4 lose 1 elo, B1 wins 1elo, B2, B3 and B4 win 10 elo
the numbers of elo won or lose are just made up, since i do not know the exact way they are calculated, but that does not change anything. The point is still clear.
As you can see: if those teams match up against each other quite often and both teams win 50% of the games player B1keeps his elo, but everyone else closes in to 2800 without needing to improve the skill.
I hope that this made the issue clear to everyone.
How elo should work is that the average team elo is taken (2000 vs 1975 in my example) and every single player of one team loses or wins the same amount of points - and also the winning team only wins as many points as the losing team loses. That way elo would not rise forever, and also elo will actually tell you about players ratings.
What i would like to see from the devs is to completely redo the TG matchmaking, reset it (either to everyones 1v1 ratings or just let everyone start from 1000 again) and have it calculated properly so that we can enjoy TGs again.
