Well, a good working squad (or a few for that matter) is thé way to win the game. Medics are required so that a dead squad member doesn't have to wait 15 seconds before respawn AND because it will save you one ticket for not dying. A sniper can be very very very usefull is certain maps. The problem with snipers, is that in some maps like karkand or sharqi, everybody wants to be a sniper... in a 32 player team, you will lose with 20 snipers and 12 medics.... concerning the squad, you can be in a squad as a sniper so that you can spawn in usefull places on the map without having to walk around for 5 minutes. respawn and walk away from your squad... JUST DON'T BE THE BLOOMIN' SQUADLEADER ON A FREAKING ROOFTOP 10 MILES FROM THE BATTLE!!!! just my 2 cents :)
