Although Black Ops II is currently one of the most popular shooters, it is also one of the most frustrating games to play online. There are so many things that make veterans of the series rage which could easily be fixed. Here is what I would personally change to make Black Ops II even better:
Following the Wii U and 3DS servers being taken offline, Call of Duty Black Ops 2 and Ghosts are officially dead.
Call of Duty players are jumping into Black Ops 2 for the final time before its Wii U servers go offline for good.
GTA 5 and Red Dead Redemption 2 leap up due to summer sales
Wow, good games never get old I guess.
CoD will always be a beast of a franchise, and how awesome is it that you can just boot it up or pop it into your Xbox and play, MS BC is really a neat feature.
Penalize death. You get points for killing but not dying.
You want to make the hardest class even harder, by having the sniper require 2 head shots?
Are you insane? The sniper class requires that they take a precise shot on a moving target from far away. Having them need 2 shots would render the class useless.
Your ideas are awful.
