i used to use it with the carbon when i mained it, and then it was nerfed, and just fell out of the meta, and... yeah :(
i'm considering seeing if i can work it into an octobrush build, since being able to get as close as possible to your enemy is everything. i've come back to the meta after a while and i'm seeing a lot of potential in abilities i never used to care for before, maybe there's still a way to make it work?
if they buffed it to work in walls, i'd be happy. no idea why it doesn't work on walls to begin with?? like is there really any legit explanation for that? maybe before it was nerfed, but it was nerfed so early on...
