Hmm this is a hard question that takes some thought but in my opinion there are only a few options. As for class there are 2 options sniper or commando. Both of them for there pre game perks. Both of witch allows you to start on the field which is an amazing advantage. As for primary and secondary it is very much up to you. Make sure you have at least one grenade in case they have a shield and a knife if you both run out of ammo but your gun in my opinion should be reliable and accurate. I've won a few gulags with one shot out of my Kronos.
