I can feel VH even now sjy rocketing up the noob scale, i think u hav eco and codine mixed up, an u dont really need code names for these things also on a DE map the spotter can usually see where enemies have crossed into bombsites, with the exceptions. Sending people around on there own is generally a bad idea u shuld sick together and attack 1 bombsite. I thinkyou should just concentrate on learning 1 map at a time, D2 is the obv place to start
