Not sure what to think of claymores. They are fun, off course, but they have a really low rate of fire, for a riot. Maybe the impulse is a bit exaggerated...
Also, skeeters have really low dps, early in this game I had a bunch of skeeters which disarmed a typhoon, and then took ages to take it down. They should get more dps, or a unit that can keep up with them to provide this dps (synergy=fun). (it is a bit like venom used to be, before redback existed)
