Pretty much this. Me now and me last year 2 different BF2 players, i would destroy myself from last year. Also knowing the map, if you dont know map you wont have much luck. Most players know map and know where you can hide or wheer to expect you to come from. E.g there is one spot at Zavod where i always plant claymore, i get at least 5 claymore kill coz people keep running into it I know that now, skilled platers know that there might be claymore, noobs dont.
