it wont be though. not anymore.
theyve reworked them several times and made them more worse, silent attack bit from 10feet away an where the heall is their hitbox I still havent figured it out, you will get bit. you will shoot them multiple multiple times and still dont die.

their original inception was each bite was 50% health. 2 bites dead, an they always came in 3's. thats what they thought was ya... good, bout right.
they have made their bite less damage but theyre attack silent and many many shots to kill.
try a shotgun or an automatic machine gun turn up the volume learn where they are an how many, jump off/out of vehicle get on top of something and open up on them from as far away as possible an keep shooting, they die hard. they clip thru u, bite u anyways, go another 20 feet behind u and then die. a full mag an still get bit.
an hope they dont "rework them" any more worse.
bottom line is.. they dont care. they think its good to go as is.
