Before you call me delulu, hear me out
Almost everyone puts at max 1 person (sometimes 0) on B,.
cNed smoke + dash, comms players location. Worst case they trade out cNed, now they have B site with a choke walled off and so much util to hold the site.
Lets say a team decided to put multiple on B after realizing their plan, cNed dashes, sees multiple, dies? Just open door and run C. Now u can wall off a choke and you have so much util to hold site/play post plant.
All went wrong? We can just aim diff players holding site
