People can come in, play for hours, or come in for an hour then leave.
That is the appeal to me. On off nights when no one is around, or there are only 2 or 3 of us, EVO just fits the bill a little better than a real tactical mission. Plus, there are very few missions on the server that are good for only couple people. I know that some people are working on some smaller missions though.
And it is possible to clear a town by yourself. I did Obregon this afternoon with just myself, my AI and my various sniper rifles as I ranked up. It took about 1 1/2 hours and I quit with around 100 infantry kills to my name.

Of course, as soon as Nixer got his sound issues figured out and then adlabs and +G got on I had to go.
