Brimstone really is the last agent that needed a nerf. Since launch you've been able to sit in his smokes and hide from Raze's boombot since it would not detect you inside a Brim smoke. As a Brimstone main, this was frequently a big deal and I was able to pull of some great moves by hiding in a smoke that the enemy thought they had cleared. It also made my smokes feel unique and useful. To randomly remove this Brim smoke functionality in a recent patch is a kick in the nuts to Brim mains.

On a side note, I think his iPad equip time was reduced to zero. It would be such a nice quality of life buff to Brim to be able to be more active and responsive with his smokes and ultimate without quite as much risk of being killed by nearby enemies b/c between the (1) ipad equip time, (2) placing the smokes, and (3) re-equipping your weapon, you're stunned for like 4 seconds, which is absurd in high ranked gameplay. It's not like there already isn't a delay between smoking and the smokes dropping anyway, so they'll never be comparable to a duelist's instant-jet's smokes, even without the ipad equip time.
