I see some here consider these usefull. Am I missing something with them?
They have movement of 1, and usually can't even get to the enemy before the battle is over. Yes, they have the projectile wasp swarm, which is ramage reduced due to them being so far from the enemy, but what use is the second wasp swarm (in red)? It does not appear to do anything but waste a turn????
