GFVerse.info - QBZ-191

Overview

QBZ-191's skill description is somewhat complicated but it breaks down to:

Passively causes explosions if she hits the same target twice in a row.
Each dummy targets independently during skill uptime, prioritizing High-Threat enemies.
Upon skill activation, each dummy's first attack silences their target.

All in all, this means she behaves like a normal AR outside skill, and either sprays wildly among all enemies or focuses on the few High-Threat enemies present during the skill.

QBZ-191 should be treated as a high priority High-Threat target silencer (mostly Sniper Nytos (Snytos)) and is rarely useful outside this small but important niche.

Pros

Highest Threat Targeting

Picking off the correct targets and not wasting time shooting irrelevant low priority tanks is amazing.

Silence

Preventing Snytos from jumping back and using their piercing shots is amazing.

Cons

Very Much A Specialist

If there aren't important High-Threat targets for her to focus down and eliminate, you probably shouldn't use QBZ-191.

Full analysis

Due to how QBZ-191's targeting works, if there aren't any High-Threat targets she will just spray randomly and is unlikely to proc her passive AoE, meaning she is not doing anything useful. As such, she should pretty much only be used if there are important targets for her to focus on.

In very high difficulty content where Snytos have more HP and possibly Force Shields or HP Shields, QBZ-191 alone may not be enough to kill the Snytos in time, requiring support from another DPS to kill them before the silence ends. Even if she can't eliminate the Snytos on her own, so long as the silence is active, the Snytos cannot jump out of range immediately upon losing a link, making them possible to eliminate.
