This is simply not true, isn't it? Theres almost no reward in leveling up. As game is right now, to get in lab and have it easy, you need 1) gear 2) buffs 3) good foods 4) potions.
You can get into lab on lvl 1 - 60-70 true, but you won't be able to kill 2-3 mobs without a proper set of gear and that is at least purple-yellow of lvl 60 (not enchanced) and it won't be very easy. Now easy is probably a set of max enchanced augmented lvl 70 yellow gear. Go grind for that first, lol. Not to mention the meditation/calligraphy/whatever to be more effective. I want to repeat myself, simple lvl-ups providing a player character with enough power to feel good in lab is simply not true as of now.
Yes, for you, no doubt. How much time do you have "invested" in this game (/age)? What is your gear/skills? Don't tell me you're using lvl 50 red set of gear, lol.
The game mechanics is simple, grind, grind, grind while lvling up so that you can buy all the abilities and craft a good set of gear. Plus grind some more to add an extra mod and reroll it.
Sure, after playing this game for a year you can feel that the first level of lab is easy to solo. The dungeons in this game are designed to go in with a large group, not to solo. Even then, sometimes, monsters respawn too fast for your group to handle if the group is not maxed out. (without burying).
Problem is, when a newbie comes into a game and sees characters like say, Aws, Monger, etc, he thinks, wow, I'll be that powerful soon, but nope. Lvlups are almost useless.
On the topic of cold, it's just the same stuff. Meditate for cold resist, get universal mitigation (bc) and craft a set of good winter gear to be able not to freeze and to fight in winter locations. It's all not that fast and easy in terms of time, so not really efficient, because you can go ilmari/rahu and other non-winter higher lvl locations, that will be added to the game in time and farm there. So, what's the point to waste your time on winter gear and other stuff? You can get to NPC's to unlock caps without any of that.
Right now, it seems like it makes sense because Gazluk is the high-end zone for now, but it won't be the high-end when the game is complete. So another "skip it" location in the future, just like the majority skips farming in Kur outdoors today.
