Is there a reason most people dont deal with heavies?(Bugs)

I like the RR but wanted to try something else....mixing up my loadout. Just to realize that if i don´t deal with all the Chargers and Titans no one is and we get overrun everytime.

Feels like a ,,i dont care,some one else will take care of it mentality,,.

I often join games just to see in the loadout screen that we have no serious AT options and every one goes into panic mode once the chargers roll up.

Railcannon, Rocketpods or any other orbital/airstrike are NOT a good replacement for an AT weapon like RR,Spear,Eat or Commando. At the rate they spawn at the moment you maybe kill 2-3 heavies.....great now you are on cooldown and the next 2 impalers, 3 titans and 4 chargers move up..... a died,c died, b died.....a b c has left the game....gg

Why wont you fight the big guys? I just don´t get it.
