Sort of agree with your post but, part of my issue with a lot of the comments here is that they're just flat out wrong and show a complete lack of understanding.
Is Lost Ark P2W (or P2Progress faster)? Yes.
Can you purchase the progression through the cash shop in the way that people here are posting (e.g., buying a boost or gear directly)? No. The cash shop is purely cosmetics and quality of life shit with zero elements of P2W.
If you're viewing LA in the same fashion as you do other Asian MMOs (in that you can just buy gear from the shop, or stones to progress faster) you're showing that you have absolutely no idea what you're talking about and as a result, you're not able to actually define your position as your regurgitating information that is false.
I'll provide a hint to the good folks who believe that this is possible: go look at any stream. Find the highest ilvl individual. You won't find one that has 100 ilvl on me. I have not spent a penny in the shop. Do you really think if it were possible to swipe ahead and progress that this would be possible?
I could explain how the shop can be used to progress faster (which hasn't been touched on) but it would be an essay. It also wouldn't be relevant as, due to the gold cost of upgrading gear being next to nil in our version until T3, it isn't a factor.
