we need smoke grenades for map rotation

in most cases during map Rotation at Open spaces that does not have enough cover we get hard beamed from every direction without any solution to survive that 
other BR games offer a solution of smoke grenades (that everyone can pick) as a way to cover and rotate trough it ,
like the one exist in call of duty warzone,

very beneficial in such cases,
and being forces to only play bangalore just to do that
is very insufficient and unsatisfying in term of what you want to pick as a champion,

smoke grenades will do very well in large areas where there is not enough structure and building to rotate while taking them as cover
