Since the Season 2 update, Harpy's torso Napalm Shell got a new animation which looks amazing, but now its core ability projectiles feels like it has become more difficult to hit multiple modules compared to Season 1. Most hits are now landing onto less modules, averaging around 1-2 modules (vs the 2-3 modules avg last season), and even the ariel shot trick which used to guarantee a 5-6 module hit is only generating a 3-4 module hit most of the time.
In addition, whenever an enemy walks over the napalm pool on the floor, it doesn't affect both their leg modules that actually touches the napalm pool anymore (or at least not as often), instead it seems to just affect the single pelvic module only for some reason.
