My personal thoughts are that it can fuck off.
I apologize that I have nothing more to add but the only reason I bought the last two a total of 5 fucking times was so I could game with the lads and lassies on here. I despise the game. It's not that I completely suck either because I can pull in good scores. The connection issues and everything you mentioned above are game breaking for me and now that GTA online is out today, I have no need to buy Ghosts.
Maybe I did have a little bit to add xD
