It is all about being in a squad and spawing on the SL's spawn beacon. That'll keeo you in the fight. and having and knowing your role hels, too. Are you the medic? Perhaps the heavy gunner? Or does the squad need you to spot targets?

Its not about points but about helping the squad stay alive. Of course a lot of that comes down to a good SL who can define those roles for his soldiers.

That said I've found that all ground maps are full of intense fighting as long as there is 8-12 people minimum logged on.

If you are finding you are running too far try to look at the map before you spawn and see where the fighting is, and then spawn closest to it ... or just spawn on your SL's beacon.
