[quote name='crystalklear64']those are the only two i play now anyway but i've spent 92 hours on the game and my highest is level 4. its a little ridiculous.[/QUOTE]
Which two? Hopefully not FB because they just make life difficult for the rest of the team. Commandos are nice to have but support is better for taking out packs. Ideally, you want one zerker, two support, two sharpies, and one of either medic, demo (after wave 5), commando, or another zerker pending the map. If your team is good at cross healing or just plain good, a medic is never required.
