Just gotta add to the love swimming around in here lately.
Since the patch, I honestly haven't noticed many of the apparent changes, although I have been playing around with the hunting rifle more and enjoying that (with sharpshooter 3).
Creeping up on someone unawares and getting that shiv kill is the best. It feels so dirty and satisfying, and always a jolly fright when someone returns the favour!
I've also started playing a lot more "dynamically" recently, which has improved my game ten-fold. Changing position often, especially during little skirmishes, can add a lot more excitement and also help to confuse the enemy. Running in one direction to direct attention then sneaking and making your way round for an ambush is also fun. Simply knowing when to run/fall back and re-strategise can help if you're getting frustrated from too many deaths.
The only gripe I have is how you can often get shot when it seems like you're behind cover. This is particularly bad when backing up in a pinch, as it always feels like the last deciding bullet shouldn't have hit you... can be quite frustrating, but apart from that the game feels very fair.
My friend and I often Skype up and creep around together, which makes for an awesome online experience. Co-ordinating attacks and pulling off rescues feels great every time. I haven't played a "typical online shooter" in ages, and this one is really refreshingly different. We're currently only in the level 10-20 range, and party play often means we get landed in a game full of level 100-200s, but hey. We deal.
The coolest thing is, my wife (who is by no means a gamer) has gotten into this big time. At the weekend I was about to pop in some Dark Souls (which she has also developed a soft spot for, incidentally), but she protested and we ended up taking turns in lives on TLoU. Again last night, she hadn't had the best day at work and just wanted to blow off some steam by chucking some bombs and shooting some dudes. I don't know what it is about the formula, but they've really nailed it in relation to the single player (which she hates with a passion).
I know someone from ND who never saw the multiplayer outside of early testing stages, and whenever I gush about it they're like "is it really that good?"
Yes. Yes, it is.
