I'd expect, from the many depictions of zombies by which I have been victimized, that crawlers would pose little danger as long as I'm aware of them and don't stand too close. I'd think that, in 7DTD, I (my character) should be able to easily dispatch a crawler. A swift blow to the head, easily made from my greater height and, assuming I'm holding a suitable mêlée weapon, with my much longer reach, should be relatively riskless. Instead, I find crawlers to be more dangerous than 'walkers'!
Perhaps crawlers greater danger lies (ha) in their means of locomotion (flailing their arms) also serving as attacks. Or maybe I'm just getting too close and I should try attacking from a greater distance.
Is there something I'm missing? Or are crawlers really as dangerous as they now seem to me to be?
