The example was exaggerated. The point of it was that a fishing rod is much more effective at catching fish than a club. Daggers would be much more effective at clearing spawns than a polearm would. But a polearm is a much better WW weapon than daggers would be. Some weapons are better than other weapons for certain things. So instead of saying polearms are bad in pve and wondering if it can be fixed, use a more appropriate weapon.
