W@W was full of game changing glitches. You can only call in so many CPs before someone sticks a pro pipe up your poop shoot. Under a map, or behind a see through wall outside a map on W@W, you're invincible. Get in the rock on Fuel, see if I don't climb up from behind with ninja pro, and spray your ass. You can't really count prone or crouch elevators, they are in MW, W@W, and MW2. I think MW2 without a beta kicked W@W's ass, as far as stopping some no skill idiot from getting somewhere invincible and destroying the game for everyone. (Seelow, flamethrower, need I say more?)
As far as Black OPs is concerned, record and report options. Stroke of genius, or just figuring on an epic failure, full of breaches and skywalks? Either way, they claim to be bringing the ban hammer down.(sorry about getting you boosters all excited about the return of the TI) I personally, am hoping for, a level playing field, that would quickly weed out the noobs and cheating idiots.
