Ultimatum's "Slay Enemies" - low monster density

Fix the dogshit robots walking around not dealing damage. Slow/no AoE builds CAN'T DEAL DAMAGE to the robots. They teleport every 4-5 seconds, going invulnerable. Slow strike skill wont hit the robot, because it constantly sidesteps. Mechanic wont spawn more monsters if there isnt less than 2 monsters, so player either does the mechanic for too much time or abandons it.

robot waves are the most infuriating experience in ultimatum, to the point i strongly consider leaving the map if they spawn
