The first thing that has to be realized is everyone is entitled to their opinion. If you think the game sucks, then thats your opinion and I respect it. Not enough folks doing that on these forums.
With that in mind, my feelings on Ghost are short and simple. I love a lot of aspects of the game and I play it more then any other CoD at the moment. The game is a 3/5 for me and would be a 4/5 if they would resolve the lag comp, respawns, OP dogs, and please please for the love of God stop putting me in a huge map for Cranked! Cranked is a game mode meant to be played fast and in a small to medium sized map, so why do you have the option to play it on siege or chasm. Seriously?
Other then that, I like the game. Its really simple. If you like it, good, keep playing. If you don't, good, then stop playing. Stop paying and stop playing. Very simple.
