Just came across my mind... What if PG as it is now, was a released Single Player game? Would I cheat and how?
Well, I would certainly hack and disable Body Heat/Dehydration/Breathing and give myself a bit more movement speed. And that's about it. Perfect non-disruptive grindy gameplay for me. For Starters.
Theres also more gameplay related stuff, like going out of combat takes ages (3-20 seconds) even after you kill the target and it has to be fixed, but I didn't want to mention it yet.
Maybe, the devs, have an evil plan to add the "Ignore the weather" ability to Weather Witching for an hour @ lvl 125 that will enable you to grind full-on in places like Gazluk, etc. But it's not in the game yet and as for now, that cold mechanic is very disruptive.
Another idea...
We and the devs btw, could make a simple forum Poll and collect the data as to how many Players actually farm monsters (monsters, not mining or fishing, etc) in Kur outdoors for an hour or longer. I could even bet it won't be more than 25. (I actually saw 3-5 HIGH level players at most). It'll give the objective feedback on the cold mechanics in Kur.
P.S. Yes, Yes, I get all the ideas of being original and providing an additional challenge to players and all the other intentions and stuff...
But the fact of the matter is: as of now, it simply doesn't work. not properly, not fun, not positively. It's disruptive and makes you hate the zones. So, change it(for instance much more body heat both on character and items), give better means to beat it (cold potions that let you ignore it for an hour for example) or remove it.
