The fatal flaw with the current business model.

Then what you forget, is that nexon had a similar system to what you described, some skills, lets say snipe for marksman, originally needed you to have a quest item that was dropped by bosses/mobs. Even when the items were available to everyone to find from said bosses/mobs, they were extremely rare and hard to find,I remember how much time i spent grinding at mobs trying to get the green book for my marksman snipe, or how many cwkpq i went to to get the book i needed to get the skill

Dont even get me start on el nath pq to get dragon breath ._.

I do remember. I had a nice time doing all of that.

Why state something if it's only speculative? That's why i'm trying to get y'all to see, you are saying stuff like it's fact and it would definitely work if nexon just did this or just did that etc etc, when you have no idea how it would really affect their overall revenue be it good or bad. It's all speculative.

Well, considering I was making a quote from Min Kim, the freaking CEO of Nexon America, I highly doubt that it's "speculation" that it was at one point a company philosophy that has since been abandoned.

They are a business, they will have had to have been constantly researching different pathways for the game and trying to optimize it, to say that they are stupid and don't know what they are doing is highly naive.

Ms could be a bit better i don't disagree, but what they are doing now is working like a charm and they are even seeing profits from what i gather from the yearly reports.

They have done some pretty stupid things in the past, like verbatim copying a version of kMS, and with it, exploits that had already been solved in later versions in Korea. Not to mention some evidence of lack of research in general, including lore inconsistencies.
So yeah, I'd say that on any given day there's a fairly good chance they have no idea what they are doing.

Also bear in mind that there's a difference between revenue and profits. Furthermore notice that the trend has been a continual decrease in revenue.
