Again, Vids or it didn’t happen. It’s so cool when people make odd claims and provide no evidence.
And my win rate is irrelevant. You don’t have to be good at the game to have knowledge. I have physical limitations that make the game more difficult to play. Doesn’t mean I don’t know anything about it. Knowledge doesn’t automatically equal skill. But go ahead, feel free to name shame so I can report you for it. This game is a talk-crap simulator. All anyone ever does is moan and complain here, moan and complain in game, rage and moan some more. Then maybe flame and troll other players, then come back here and complain more. Why are you all playing if you aren’t having any fun? lol
So yeah, about those 1500 MMR losses. Still waiting to see the evidence. Since you’re not doing it, I’ll go ahead and investigate this further myself 
Here’s a snippet from the rank 1 player’s 4v4 history (disclaimer: This is for illustrating the point, and not to disparage anyone - If this still tests the limits of the rules, I can strike out the usernames from the images)
In all the games visible to me, he’s got a few losses with ~ -100MMR and some gains in the 50s and 60s, and a few obviously skewed matches he was heavily favored to win where he only gets +2.
But none of this is out of line with what I would expect for the rank 1 player. Literally everyone else is below him, so he’s going to gain less for wins and lose more for losses.
Here’s another top 4v4 player and known player on this forum. Again, no disparagement intended (And happy that their own claims about their performance were true)
Heck, he’s at 7100 MMR and I’m seeing wins over +100 and no losses over -70 or so. Nothing unusual here.
I’ve browsed the profiles of several top players in the leaderboard, and not seen any “-1500” MMR changes. So that means either
- you’re exaggerating (“1000” = 100)
- You’re making it up entirely and just trolling
So yeah, I might be completely trash at this game, but I have these lovely things called eyes and they don’t see anything that aligns with what you’ve claimed in this thread.
