I've been playing 7d2d since A10 back 2014 ( over 2000 hours over the years ). Since than game was getting better and better with every update. Really open world sandbox with no limitations except the RNG gods

I liked that part even if I couldn't find those "damn" calibers till day 100 I didn't care, I played melee and bow - since than I always play with these two I don't care about guns much now

, only on horde nights mostly.
Didn't find forge book, no biggie Quality Joe jumped in to help me out and so on, no minibike book, OK i ll keep my eye out for construction zombies and bikers.
A17 brought many good things, but took away the backbone of A17.
I like new combat, additional perks ( I always felt archery was left out with extra skill - Boom headshot and sneaking perks are awsome now in that regard ), I like cooking also got some love ( though I still miss some more advanced kitchens and recipes, seeds variety.. ), Vehicles are great ( believe it or not bicycle is my favorite ), new POI's are just awesome and beautiful, landscape is nice ( RWG is work in progress I know ) and many other things.
But the main sandbox thing of A16 was a zombie survival feel, where zombies were zombies ( slow, dumb and just looking for some fresh piece of meat - thats what the definition of zombie is! ). I know new AI is work in progress and all, but zombies doesn't jump or solve maze puzzles etc.. thats a completely different mob - I have no problems with dealing with them, but it doesn't feel right as a zombie.
Weapon parts were nice, sometimes RNG frustrating for not finding that last piece for sniper rifle - but hey you adapted. It would be great that would be kept ( quality levels may remain the same as they are now 1- 6 to simplify things ) and once you would assemble the gun it would become the item as it was introduced in A17 and mods can move in. That would be an awesome upgrade to A16 system.
Blades should slice through them and chop their hads off and not that it feels like hitting the with a stick - I know there cant be hordes of zombies because of performance issues, but blades should feel like blades. AND NEW A17 HITBOXES!! I mean poke and shoot style... also big dislike.
Building was one of the strongest parts of the 7d2d, it took a huge step back and with it whole gameplay. I liked building bases with traps since day 1, for zombies dismemberment so you could prioritize to whom you would attend first. I don't mind zombies rushing in and attacking the weakest spot, which of course you can turn to your advantage, but zombies with a mind of an architect - that is not a zombie any more. I wouldn't mind for some special boss zombies or something alike that could do that ( some super mutant sort of thing ), but zombies should remain zombies.
From day one horde night never felt the same - yes in B195 things got very interested ( unbalanced at that time ) with new vultures coming in and spider zombies started jumping from the ground to the parapets ^^, but it felt more like some shooter game and with few tweaks they were very predictable and not like old mindless types from previous builds.
This new AI should be kept for bandits or some other new type of enemies. Oh and spider zombies should be creeping from dark corners on ceilings dropping down on you while looting - that would be more immersive looking up and all around during loot runs
But the main dislike is the new perk system and gates ( not pregression in damage type, but more like forge tree, schematics, science... they contradict each other - you unlock something yet you cant do nothing till level 70 since you need steel? etc.. ) . As I said earlier A16 had a great skill tree, which should just had all the new great additions of A17 integrated into old system. Athletics was a great example of it - more you ran, jumped, punched more athletic you became ( so with new perks you could integrate that for stamina usage - the more you are getting fit with all that the less stamina you would use ( like in real world ) and all the agility perks from A17 would mesh great with athletics. Same with other ranged and melee skills. A 16 had a great foundations and it would with some trial and error with adding A17 system to it implement it to being even greater.
AND NEAR DEATH debuff is poorly implemented - yes you should get some debuff to stamina and health, but you should have way to mend that with food or medicine. And you loosing skills, wtf?? Thats so poorly integrated - fixed 30 min time with no way to fix it...
There are many things I like about A17, but it feels like the game lost its charm it had and turned more into shooter action style gameplay and lots has been cut away from the A16 good sides. All the tactical aspects, building aspects got somehow dumbed down instead of improved and refined even further ( would love to see some end game settlement rebuilding to create safe zones for survivors - at least I had a feeling that was the direction game was going ), but now it feels more like it steering into action style gameplay, where mostly quick trigger finger on a mouse and hand reflexes plays bigger role than the rest of the game - smart builds, exploration, outposts... of course all there are still here only to much smaller extent.
You got many options in base defense building - from pillars, poles, ramps, stretching them out, shooting or melee... now all that is far from what it was. And yes I know AI is a work in progress obviously, but it just doesn't feel right.
There are many other things I could write about - as an "older gamer" I never ever got involved much in game discussions before, but 7d2d brought me back to gaming world when I found most of the other games out there just plain, repetitive already seen before type of products that only developed new graphics but ideas behind it remained the same. Many games tried to imitate what 7d2d had but failed at it.
With A17 it felt like that something that I really enjoyed somehow steered into wrong direction towards above mentioned type of gameplay. Of course there are many different players with different tastes, but this is just my opinion and my thoughts to give for some consideration.
