This game is ruined in 2s. Axis always having to respond to allies game play (no im not being a one sided fan boy)

Your playercard tells otherwise. You have almost zero games as Allies compared (even in AT games) to your number of Axis games and you seem to be on a losing streak as Axis at the moment so I sense some salt; unfortunately it's a little hard to take you seriously especially when you pretend not to be one-sided. Like I always say, it's absolutely fine to have a favourite faction (who doesn't?), but before getting frustrated, try playing the opposing faction once in a while and see how the emplacements are countered.
Emplacements are high-investment, but they are designed to give strong control in an area; once destroyed you cannot get any return unlike squads which you can retreat. You have to take emplacements out quickly before they reach sim-city critical mass; I've noticed a lot of people don't defend their initial investments so move up quickly.
As OKW: 2xLeIG will destroy any emplacement; the only real counter is standfast. Also raketens + shrecks + flame nades
As Ost: flame mortar, AT gun, pregrens, flame HT, flame pios, AP incendiary if you can get close enough, etc.
