This is an interesting idea, but not one that I see happening, or that really needs to happen. As an Octobrush main, I think the Octobrush is a fine weapon as it is, but when it comes to the Inkbrush, there *is* one thing that I think needs to happen.
Namely, fix its damage! The Inkbrush actually deals less damage than it should most of the time. Normally, it does 28 damage per hit, resulting in a four-hit-kill. However, when flinging it fast, which you basically
have to do to use it well, it actually deals less damage than that pretty often, usually resulting in an actual five-hit-kill.
The following video demonstrates that when flinging at max speed, only 3 out of 21 flings do the full 28 damage. One hit may not sound like that much of a difference, but it definitely is, especially in close combat situations like you get into with the Inkbrush. As seen in the video, other rollers are affected by this as well, but it's clearly intentional, as it does not happen until after the roller has done 100 damage. With the Inkbrush, however, it happens
four times
before doing 100 damage, resulting in one extra hit-to-kill than it should require. This mistake really needs to be corrected in an update very soon, as the Inkbrush is already a difficult weapon to use as it is. It doesn't need an accidental damage nerf holding it back.
