I love this game when playing vs another player. An I really like the first few solo scenarios when there is no hidden units. But in the scenarios with rumored units (sometimes a few, and sometimes a lot) I tend to sit around drawing cards for rumored enemy units while the few units I started with are all spent.
What am I doing wrong here? Am I supposed to pass a lot so my units doen`t get spent or am I doing something wrong handeling the rumored enemies? I have played this game a lot less lately because of this. It´s not fun playing rumored enemies most of the time.
I can't tell if you're playing something wrong from your description so far, except perhaps you're not revealing the rumored enemy units when you should be (as soon as they are out of cover and visible, you should reveal what they are), and this would eliminate some of the rumored units.
If you are playing a more defensive mission, then yes, you'll want to pass more, although that is generally the same in 2 player games as well.
