Bofors is trash because it's an expensive static shitpile in a game that emphasizes moves and flexible tactics. Same goes for bunkers, command hqs and other shit.
yeah except bunkers are far faster to set up, smaller, considerably cheaper, easier to get, can be gotten earlier than a bofors
you normally get 1 bofors, but you can shit out bunkers whenever you got the manpower and munitions to spam them, for the cost of absolutely no pop cap you can plug in your flank
