I am going straight to the point.
Reason # 1. campers... it takes abesolutley no skill to play the game. commando, nube tube, flack jacket and claymores. the square of nubes.
Reason # 2. sounds. i know people are gonna be hating on me for this one but the sounds suck in black ops. everything sounds like a pee shooter.
Reason # 3. flack jacket. i personally belive that flack jacket is the most over powering perk. i can blow up a car that some one is t bagging on and it wont kill them.
Reason # 4. DLC. all of the dlc suck, one good multiplayer map comes out of it and a good zombies map too, always.
Reason # 5. silencer. if i put on a silencer it will take me 2 extra shots to kill someone. it say it takes down range but it actually take out damage.
Reason # 6. through wall kills. it takes an entire mag to kill someone through the wall, espically if you are using a silencer.
Reason # 7. sniping. sniping is the worst in that game because if you target is moving at the speed of smell and your crosshairs are right on him it wont hit.
Reason # 8. snipers. im pretty sure that if someone gets shot by a sniper then he will defiantly die but 50% of the time it takes 2 hits.
Reason # 9. nube tubeing. some how Mw2 tubeing is a lot more tolerable than black ops but if you dont have flack jacket you are dead.
Reason # 10. guns. all of the guns in black ops are either the SH*T or they are total and utter crap.
Reason # 11. last stand. worst perk of all time. MW2 did it right no getting back up afterwards. but in black ops they can get back up. and i realise that is only after pro but still. Mw2 pro use of equipment. and there is also that stupid thing when i shoot them and they go down but they still knife me from a mile away. GET A REAL PERK
Reason # 12. last but not least knifing.i swear that i am an inch away from someone and i still cant get them if im not using ballistic knife.
