Helldivers 2

Interesting video and worth watching. The TLDR is that there are now more small bugs and less Bile Titans spawning since the latest patch. This makes the flame thrower and Breaker Incendiary much more relevant alone. However, at higher difficulties they also now spawn Charger Behemoths, which have more health and head armor than standard Chargers. These require 2 headshots from a Quasar or EAT, making those weapons less relevant. However, their legs still take the same amount of damage from a flamethrower as a regular Charger, so they can be burned to death in like 3 seconds.
