They probably thought that Goulash was the way to "fix" Dragonspine once the quests were done there. They should give us all a tool that prevents cold buildup after this current event there. I can't imagine them going back to it three times for major events, but I guess we'll see.
I don't personally mind the cold buildup mechanic, but it seems to not be very popular at large. One of the things I like in a big expansive game is when areas actually feel dangerous. In FFXII, there were those dinosaurs right outside the starting town. That kinda shit makes me happy. If anything, I wish we could manually toggle some of the areas we "fixed", like the thunderstorm 100% of the time Island, the foggy island, etc. I also wish we had wandering randomly spawning "world bosses" that drop cool shit like prototypes or whatever, but are extremely hard to beat.
It's part of what I used to love about FFXI. The whole world was actually dangerous. Even at max level, there were numerous areas that you had to sneak around in to avoid death. More games need dangerous worlds like that.
I think it would also open up the combat and teambuilding a bit. To be clear, I'm not talking about damage sponges or 1-shot mechanics, I mean legitimately fair but hard difficult enemies or world mechanics.
