Very hit and miss for me. Currently level 34ish so not a ridiculous amount of time played, but enough to get a decent idea of what's what.
The winning team is decided by who has the upper hand connection wise, no two ways about it. Whether it's the lag compensation dragging down superior connections to lowest level or what I don't know, but if it's clear as day to see, I've been on both ends of the fight. Loads of fights I should never have won, I just went in guns blazing and destroyed everything. Loads of fights where I've got the jump on someone and after half a mag they simply turn around and kill me. Frustrating as hell, but oh so lovely when you're on the giving end.
The scorestreaks are a bit meh, and the variation is crap too. I didn't play Ghosts but I preferred BO2s style of scorestreaks: lots of them and very varied. This just feels crap. They are also pretty underpowered, although I must admit that adding an AI controller to some does help, the gunship thing with the AI pilot (not the paladin, the smaller one) has grabbed a few kills for me.
The game just feels too fast. Spawning in and instantly running makes everything all shaky and whatnot, bloody awful. Coupled with all the jumpy nonsense and I don't feel like a soldie rany more, rather a duracell bunny on crack. It's bloody awful.
The spawns are another terrible aspect, my very first game I jumped in a game which was in progress with some mates, and ended up on the enemy team. I got killed and respawned at exactly the same time as one of them, and we spawned in about 6ft apart, looking at each other. Shocking. That said, I've since stopped playing KC and play almost exclusively domination now which seems to have better spawns and is considerably more enjoyable.
The thing is, it's Call of Duty. It's the biggest name out there and despite all it's shortcomings it's still a fun game to play, if somewhat infurating. I must admit that the community in this game is beyond awful. Losing Domination games because your team mates refuse to leave their camping spots, losing KC because they refuse to collect tags, that kind of thing. I can understand new players needing to find their feet, but people who deliberately lie in corners and on roof tops with thermal scopes just irritate the hell out of me, especially when we're losing because of them. Get off your lazy bum and cap a flag dammit!
A massive fail for me which is more Playstation's fail is the party chat. I miss all the old trash talking from BO2, met many friends like that. The lobbies in this are just silent as everyone's in a PS4 chat which for me at least, takes a lot away from the game.
Nevertheless, I do enjoy it and will continue to do so. I find that ignoring stats and jus getting on with it helps. Also, leaving games which are unplayable. My gaming time is fairly limited nowadays so rather than spend 10 mins in a game which is making my blood boil due to crap connection issues, I'll simply leave and find another lobby.
If anyone needs a mediocre team player, feel free to add me: D-i-d-d-u-m-S
