And since it's a channelled effect, just like Dragoon LB, you can just guard and negate it before the Gunbreaker can even activate the stun.
Unless you managed to purify a CC immediately before you activate LB giving you immunity, which doesn't make you immune to knockback anyway, you cannot rough divide in and get the LB stun.
[4] The LB is heavily reliant on server tick. Your move speed boost from Rough divide will not make up for the fact that someone can literally walk away before the stun goes off and you won't get the stun even if your client says you are right on top of them.
The LB is a Gunbreaker's only source of CC. If your opponent has their purify up, you will not be able to CC them, which results in situations where an opponent can get hit, cleanse, then run off to a health pack.
