i remember why black ops 1 was my last CoD game... after 4 months you'd refresh your server browser (PC) and 23 out of 25 maps would be nuketown. spawn, throw nade, die, repeat.
and all of this cause CoD fans are so rabid to get XP on this invisible treadmill. they take away the basic ability to actually select the gun i want to use, which i have already unlocked, during the match. they take this ability away and then dangle it like candy at the end of a long stick above the players head: "well you want up to 10 custom slots? you just have to grind level 1-60 over and over and over and over 10 times, not too much to ask right? just make sure you sink absolutely all of your time into it because there will be another half assed sequel to buy next november so you can just repeat the process all over again"
