How was it impossible? You could get plenty of water without ever looting a town. You had the option to drink water from any water source if you wanted to and you didn't have to go to town in order to build a dew collector except for one version when you had to buy a filter that was only from a trader in order to build a dew collector, but that was removed quickly. It wasn't impossible to stay in the wilderness and avoid towns. Besides, most people who choose to play a wilderness-only game still loot wilderness POI. Dying from thirst isn't even an option in the game, btw. Not unless you consider dying from bad choices when fighting and not have great stamina regen because of thirst as "dying from thirst" even though you could easily manage that if you needed to.
Again, you're not going to die from thirst. And there is zero reason to buy jars from traders. I don't even use the empty jars. There's no need to. I don't even have a dew collector yet and I still have not needed to use a single empty jar. There are plenty of options for managing thirst without needing any empty jars. And for those who can't figure out how to do that, enabling jar refunds will give you so many extra jars pretty quickly that it's hardly a problem. I mean, a single empty jar with 100% refund will let you never be thirsty unless you have no water sources around because you can just keep refilling it over and over again. The only real reason to buy empty jars is if you want to make a ton of glue, which comes back around to the original reason many of us have been saying that people were asking for empty jars... glue production rather than immersion.
If you're saving jars after use, you're going to have endless jars even without dew collectors. As I said, I haven't even used any empty jars, so I already have more than I need and I haven't built any dew collectors yet. Besides, if dew collectors bother you, just don't build them. Leave them for those of us not interested in using empty jars. You got your wish for empty jars. Now let those of us who don't want them be able to play the game without them without needing mods.
That may be true, but you can honestly say that if it was the end of the world and you were looting houses and buildings that you would have any difficulty finding bottles (water, soda, juice, energy drinks, etc.)? Not to mention every other container that can hold water? Yes, you might not have any, but almost everyone else will. It actually made more sense that the jars were abstracted because they are so easily found in the world that making it as if you always have some handy when needed is more realistic than making it so you have a "hard" time finding them.
I would point out that there isn't anything that I've seen while playing 2.5 EXP that tells the player to wrap up the meat in paper. Anyone who doesn't follow the forum or patch notes is unlikely to ever wrap up meat unless someone tells them about it. To me, that makes the mechanic not a good mechanic. It isn't clear and doesn't even make sense. After all, an animal can easily smell meat that is wrapped in paper. That has little to no effect on them smelling it. We're not putting the meat into ziploc bags here. Anyhow, I don't really care what they do with smell. I've played around with it and I'll finish the game with it, but it hasn't added any value to the game and just gets annoying. Not to mention a RED icon always on my screen whenever I carry raw meat or eat something is really annoying to see. So I'll end up disabling it after this game and never use it again. For those who like it, that's great. But I have no reason to use it.
There isn't any reason to worry about the paper. I haven't bothered wrapping up meat. It isn't too common to have raw meat in my inventory in a large town and it's hardly a big deal to have smell in the wilderness. I just carry it until I get back to base and drop it off. I'm not going to carry around paper for such a minor thing.
