I don't understand how this does anything for the 'survival' part of needing water. There are magical vending machines every 200-300 meters that have plenty of fluids. You can drink straight out of the water source and there's many ways to prevent, treat any sickness. I haven't needed or used a dew collector, myself. It's definitely not good for immersion to be near a lake and not be able to dip a glass bottle in it to collect the water, or not capable of melting snow. It doesn't feel like you're 'surviving' when you can just pop in some dukes in a vending machine and get anything you want to drink.
I'm not a fan of the way the water is, but I can live with it. It's definitely a downgrade to me though. It feels backwards. It feels even less like survival when you can't even do the most basic thing of bending down into a water source and collect it.
In my perception, making it take way longer to create glass jars and making them more rare could have slowed things down enough. I'm not even slowed down by water at all as it is now - there's still water everywhere.
I think this is the biggest frustration to me.
I remember at some point jars being low drop rates. Playing with friends, we'd have to manage jars early on because we had relatively few (and they were still consumed in cooking). At some point, the jar drop rate was boosted, as well as things that contained jars/gave you jars when consumed.
Now, the dew collector/water change seems to have been made to make this actually something you have to manage...
...EXCEPT there are Traders and Quests in the game now, and you get TONS of Murky Water by just looting. If you aren't getting any, a Tier 1 quest gives you enough Dukes to buy 2-5 drinks from a Trader/Vending Machine, and those restock every few days. Every Trader also has a Vending Machine. The average Vending Machine I've found has around 10-15 drinks in it for 120 (Water) up to 600 (Bootstrap, Smoothies), meaning every Tier 1 quest I do (can do 2-4 in a day) can get me AT LEAST one drink, and at most 5, and the Vending Machines and Traders restock often enough that they never run out.
"Ah, ha, but the nerf was only intended for multiplayer!", you might counter.
Well, first off, that's just wrong. Second off...there are more Vending Machines in the world. Find yourself a POI with a working Vending Machine to turn into a base. Now you have water for life without even making a dew collector, even if other players are emptying out the Trader inventory and Trader Vending Machines. And Vending Machines aren't exactly rare.
Between Vending Machines and Traders, the change to water was completely irrelevant.
All it's done is make it where you HAVE to quest to be guaranteed water - either through getting Dukes to buy the filter, or getting Dukes to hit up the Vending Machines - and that's it. It hasn't actually made water survival more difficult, it's just forced people out of crafting/basebuilding playstyles and forcing them to quest. For people who already did a lot of questing before, literally nothing has changed for them.
Which might be why so many posters who prefer questing and running POIs are saying they don't see the big deal. Because, for them, nothing really has changed.
