Why was H4's multiplayer disliked to that extent?

Well sure it had it’s flaws like any before it, namely the sprint and swords for the infected are forced into you no matter what, not being able to drop the flag (srsly who even thought about that), removing elites / invasion and the dumb hit markers come to mind. And of course the way matchmaking was set up for most playlists was a complete disaster that tried to copy COD even more, and dual weilding was abscent once more, but these 2 problems weren’t knew so I can’t blame 343 there. If you are mainly into matchmaking I could see why you would be very annoyed but other than that the amount of negativity it recieved is illogical if you ask me. Or did I miss something?
