The problem with a squad alternative mode replacing squad as primary mode

much of the game is designed for squads
----------Many units would be too strong for one soldier
tanks would be far too strong
snipers would be too strong
flamers would be too strong

ap mines would be a cheap kill
as would impact grenades
Molotov’s
gas grenades

a few units would be better
medics
rider
at

a few would be worse
radio
mortars
without bots almost useless

bigger issues
monetization (who wants to buy one soldier)
no good skins or not enough of them
progression without the heart of squad progression
event rewards without squads
competition going from almost none to every online shooter on the market
