The way it is right now, the vast majority of AI are completely immune to pests of any kind, making these weapons(which are actually very nice at low levels) essentially useless past, say, level 100.

I can't believe that pests are supposed to be entirely useless like that, so could their pest controls please be nerfed where they exist? Pests should always be able to do at least a little damage.

Except the pests themselves don't actually do anything...meaning nobody uses them. Fires are just another benefit of using heat weapons(seriously? Extra damage AND you take out their elec? That sounds balanced...)
