FWIW, I have at least 40 10v10 games in with maybe 4 game crashes total. No offense, but it isn't the servers.
Well good for you I guess.
The problem is either their servers or at least something to do with the connection between the player and them.
My connection and computer are perfectly fine. I can play 4v4s, Red Dragon non-eugen 10v10s with zero issue. I can play practically every other game with online game with literally no issues.
Official eugen servers on the other hand are a completely different kettle of fish.
Other than on launch day every 10v10 i've tried to join has had extreme problems. Everything is fine in the lobby (except 1-2 players who spike to red ping and then back to green).
In my experience the game works fine for anywhere for 20 seconds to 10 minutes, after that numerous players are booted from the game and eventually myself. Or else the game lags extremely badly.
In one of my games (one of the rare ones that actually worked for me) the entire German team except 2 people were booted.
This all started back in Wargame Red Dragon with the dreaded 9999 ping issue caused by poor server connection. I think the same thing is happening here.
