There's a lot of anger and disappointment, and people are looking to blame something. I can understand the desire to, but it isn't really all that good of an idea. All you are going to do is royally piss off the crowd that is comfortable with 10v10, and that isn't going to change much, if anything, for the rest of the player base.
I used to love 10v10s in WG as well. They are truly wild experiences, and loaded with all sorts of shenanigans, especially early on when the sides were often somewhat balanced. You could also get some truly epic screenshots from those games, I actually got a few people to try out WG:ALB thanks to some screenshots I posted to Facebook way back in the day.
Fixing the match maker certainly needs to happen, but removing things seems like just a bad idea. Even with how it seems like EUGEN built this game around conquest now, I hesitate to even suggest removing destruction. Maybe for their next Steel Division game, but I really don't know.
