legit vs noobs/ campers (Imo)
Snipers - campers - legit(for obv reasons)
HBS - campers - what it was designed for i guess (but stil noobish to a degree, but easily counterable with ninja)
Noobtubers + OMA pro noob tubers - campers - completly noobish (its in the name really noobtube) not really a problem unless they have 1 man army pro & or danger close
C4 danger close - campers - nobish but not as bad as nobtubers (im changing noobtubers to nobtubers as they are all nobs), and easily beatable with sitrep
Claymore OMA pro - campers - really noobish, as they can kill without fireing a single shot, the claymore does all the work, and the camper does nothing butsit back n watch the kills roll in (again not a prob with marathon + lightweight + sitrep though)
Tac insert campers + tac insert boosters - campers - the lowest of the low, the fat lazy gits way to get kills, sitrep find them easiy enough, but the scumbuckets use no skill what so ever, should be happy slapped over and over again by a giant tango hand until they stop moving
in short, none are really a problem they are just strats (noobish or otherwise its still what works best for them and thats what playing games is all about) but the sniper is the only legit claim to being a camper
