Right, but YOU are the soldier. The longer YOU play, the better YOU get.
yes and no.
you get better (reflexes and map knowledge) but the soldier is always the same, gun is teh same supression rate is the same reload is the same everything is the same aim time is the same.
this system represents your soldier actually getting better at what he does like wat a real life soldier would become after beeing in a war for months at a time.
the soldier in real life will get decensetized to supressing fire after months of beeing shot at to a certain degree.
he would get better reflexes to stuff that really matters and ignore shelss that impact away from him, bombs and mortars that will not hit near him.
he would be better with his weapon cause he's been useing it for what seems ages to him, and he would of customized it and put the ironsight a just the right position for quicker aiming.
a rookie fresch in the meatgrinder ducks for every explosion, has gotten his rifle recently and hasn't had time to propeprly adjust the ironsight, will sh*t his pants first time he gets shot at etc etc.
this is what the leveling system stands for, appart from the player getting better, the avatar gets better at his job too which is the only way to represent the difference between a frech rookie and a battle hardend soldier in a way.
