Is it me or is the game completely broken?

I can't get into any lobbies. Regardless of the game type I choose, I just end up in a lobby waiting for players to join. In some cases I do get through, but then the game is filled with bots. 

When you eventually do get in a game, the balance between winning and losing is just way off. Either you win by a long shot or you lose by a long shot. Is this a map issue? 

Sometimes I empty a clip into an enemy's head and not a single shot registers. Then other times a single shot does instant kill? Same gun, same game. WTF? is this a ping timing issue? 

Sometimes in a match, one person is getting 20+ 30+ kills while everyone else sitting at 1, 2, 4. This makes no sense. Is this because of cheaters? Or are there hidden bots?

The game started so well, now all the cracks are showing and it really is frustrating to play.
