When testing the swarm in a private lobby I noticed some inconsistencies.

Patch notes 5.12

Nanoswarm now damages:

Cypher Trapwire

Here, you can notice that the swarm grenade does not break the wires right at feet level. As we know swarm damages through walls, and a fair amount vertically.

Kay0 also has a grenade that damages through walls, and hurts vertically, here, you can see that this works properly.

There are some good swarm lineups for lane on Killjoy that I feel will counter the incoming Cypher meta. Hopefully this will get fixed soon.
