As for me, I am 120(exactly!) hours in, and happily continuing playing the game. Nearing my third full playthrough, and almost got every achievement(except the last 3, realistically achievable only in the NG++).
Loved the first one, despite it being rough around the edges.
Was afraid about the fate of the sequel - but my fears have been laid to rest by now. I love just about everything about this game.
As a piece of art or fiction, the original is better, but as a video game - DS2 is a superior experience to my taste. Never cared much to do NG+ in the first one(still put in over 200 hours, I think), but in the second game, I am already finishing my second playthrough.
Expecting devs to create keyboard controls for this game to rival the controller is... Unrealistic, to put in mildly.
Just like FPS M&KB users will always tear controller users a new one, so will controller users rip a new one to KB&M in DS.
Sure you can be stubborn about it, and hammer in nails with a wooden spoon, but why?
As for durability - system is great! Durability actually matters now - in the last game it only became an issue if you spam sword magic attacks. This time, any hit of the walls/floors gives a big hit of durability. You actually have to have a backup weapon now. Some of the very powerful weapons in DS2 are balanced by limited durability(looking at you, Great Club!). This makes you aware where and how you swing. Early on, I had to call off my expedition into a zone, because I had low durability and never thought about making back ups - which is a good lesson. You may even have some uber weapon early on, somehow - but now you have to be mindful of when you want to use it, and when to hold it back.
Further it balances piercing/lunge attacks, with wide sweeps. Lunges rarely hit walls so they make such weapons last longer.
And don't get me started on the DS1's repair mechanics! It was the most annoying thing in the game - every time I rest, I'd have to go through a bunch of menus to repair EVERY single piece of gear. What a bloody waste of time!
I had to spend an attunement slot just so I always have Repair spell - otherwise I'd snap and shoot myself/monitor, rather than go through repair process AGAIN.
Durability damage is also now an occasionally useful PvP thing. You can even build a char around wrecking gear - which is neat.
