Most of the problem with Pulsars against monsters, in my experience, is that they knock monsters out of the way of other knights' attacks. This benefits the Pulsar user, because then the monster is in the right range to get hit again by the Pulsar.
So, if EVERYONE in the party used Pulsars at the same time, wouldn't the knockback benefit everyone?
Is there some other problem with Pulsars that I'm missing? Why are they so unpopular?
