You are coping hard sadly, and I doubt I can fix you.
Randos vs AT is especially cancerous on COH2, since being better coordinated than your opponents actually wins half the battle. And judging by the average IQ of the average random player, chances are bleak on this one.
If anything, it would fix the game. I would gladly trade in "losing" the miniscule amount of arranged teams that unironically play COH2 hardcore for "winning" a fairer matchmaker for everybody.
I think you didnt understand what I was saying. AT vs randoms is a non-issue because you can count the amount of actual tryhard-squads in CoH2 with 1 or 2 hands. The rest of them are some casual noobs playing together who either dont use voicechat or who talk about what they had for lunch today.
I win at least half of my random games versus arranged teams, because it's teams like this which you meet many times:

And keep in mind this is a "top 200" team of 4. No matter who my teammates are, it's pretty much a balanced match.
"Better coordination", yeah I'm sure Random McGee and his casual friends who play coh2 for 3 hours per week are gonna pull off some insane plays against you. And for the rare case you meet actual tryhard squads with bad teammates, you do the exact same as when you get trash random matchmaking: surrender or leave after few mins.
