Protip: Whining about pointless ratings makes your point look weaker and overall, a joke.
As for your actual suggestion: No. Smoke IS quite useless, i'll give you that. But, as Cream said, its FUN. The idea that smoke is some actual useful tool for getting around traps has some weight because it does take up some area and blindsides the hale but it is never legitimately used for baiting out the hale and is solely used for fucking over team-mates.This isn't a bad thing as it provides FUN. Deathrun has already removed most of the features that provided a fun experience and the unnecessary removal of smoke suggested by you would just add to that.
I would also back up Callum's suggestion: STANDING STILL AND WAITING. Yes, I get it, there are some times where pyros like me activate smoke in an area where you can't wait it out, but even in that situation: get good. At worst, the smoke delays your commands because of the FPS drop. It takes up a small area and all you need to do is account for the slow it causes. I do it all the time and I'm usually the one causing it. It is not that hard.
Another thing, why remove it just because people are using it to fuck over team-mates? What about the small minority of people that use it legitimately? I really don't get the purpose of this suggestion other than you're annoyed that you keep dying because of the smoke command rather than waiting it out.
