So every time any one of the many players give negative feedback on here they get called emotional, aggressive, combative, are told they dont know the game, are playing it wrongly or that its alpha and any of a multitude of other reasons why their feedback is not wanted or wrong.
So here is some factual feedback for you.
1. Tools
Previously a player could find, make or buy, tools of different levels of quality, this is a fact
Previously a player would progress from poor quality tool to eventually Q600 steel tools, this gave a long progression curve and every time the player found, or bought or made a better tool they progressed, this progression was satisfying.
The new tool system means the grey fireaxe does the same damage as the purple fireaxe, sure the better quality ones have more mod slots but more are hard to come by and are random in what you find. Other than durability there is zero reason to want a better tool than the one you find in a random container on day 1, this damages the players sense of accomplishment because their progression is extremely limited.
2. Guns
Previously a player could find, make or buy weapons and weapon parts from Q1 to Q600. In order to put a weapon together or disssemble it you needed to find instructions on how to do it (schematics). When you found a new part or gun that was better than your current one you progressed, this was satisfying.
Now the gun thats level 1 and grey that you find one day 1 does the same damage as a level six purple one, it has less mod slots but again finding mods and or schematics to use/make mods is random and rare and cannot be counted on therefore you have no incentive to try and find better guns and the fun you had from continually working towards a high quality gun is totally gone
3. Armour
Same argument as for guns and tool, you took away the progression
4. Exploration
Many players like to explore the world, finding new places is fun, discovering new towns and cities is fun, some players like to build far out in the sticks, some like to find the 'perfect' spot for their base, this is fun to many players.
A combination of massively nerfing stamina usage and regen PLUS the removal of all the useful stamina drinks and the mass nerfing of coffee and beer means that you cannot now run more than about 100m without being out of stamina and having to rest constantly, this is not fun.
You have massively nerfed exploration and taken away that choice of gamestyle
5. Claim stones
You have limited all players to one claim stone and therefore hurt both you pve and pvp playerbase because now the players who like to build large elaborate bases cannot do so anymore because other players can destroy and grief them. You have also massively negated the usefulness of claim stones because only having one it is trivial for an enemy (pve or pvp) to count out the location of that claim stone and easily remove it.
This change takes away one of the biggest fun elements (large scale building) from the game
6. Zombie damage
You have greatly increased the damage zombies do to blocks and this combined with their changed AI means that even a reinforced concrete base is useless against a horde, they just chew right through it. This invalidates the desire for a player to spend a lot of time building a base when they know the zombies will just chew it up
This change greatly reduces the base building aspect of the game
7. Digging zombies
Many players of all types preferred to choose when and how they fought zombies, by some players building underground they gave themselves choices on how they played that did not, ever and in any way, affect other players, by making zombies magically know you are hiding at bedrock you took away this play option completely
8. Bedrock depth
Many players liked to build huge bases surrounded by moats at bedrock and then filled in these moats with spikes knowing that the fall would kill most (not all) zombies. These bases took enormous time and effort to construct and the sense of achievement when finishing them and having excellent defenses was a source of pride for many players. By nerfing bedrock depth severely and reducing fall damage to zombies you have remove this playstyle option for players and removed the players choice on how to protect themselves
9. Level gating perks
No objection to the perk system itself however it is gated by having to spend points to buy them, it is further gated because you have to buy the points in a perk tree in sequential order. To then add completely arbitrary level gates to this totally removes the players choices for specialisation and it is a punative and deliberate blatant ploy to slow the player down
In A16 you could and players did, choose to specialise, you have removed this from the game
10. Death penalty
Previously the penalty for death was reduced health and the run to get your bag back, I dont recall anyone complaining about this and it was well balanced. Now, even after your partial reduction of the death timer debuff the players are horribly punished for dying and this in a game which has many situations seemingly devised to give you no chance to live (traps in POI's, random dog or wolf hordes popping next to you, ferals on day etc etc)
This punishment is over harsh and discouraging and demotivates players from playing.
In summary you have removed the choices of players in many areas, you have removed the base building, the choices players made in how to fight, their ability to fight, their ability to be creative with large bases, their sense of progression in many many areas and increased the grind by (subjectively in my opinion) about 300%.
You have done with at the same time as adding precisely one end game item (Jeep) which many players wont even bother with. You did not add legendary weapons or armour or tools, you did not add bandits, you did not enhance electricity.
You have ruined the fun element of your game for a large proportion of your playerbase, I have 53 friends on steam who used to play 7dtd, this week i saw 'one' of them playing and when i asked around they all told me it was broken and grindy and just no fun anymore.
