new app limited, very expensive
There is a huge demand for limited apparels. Check out PKO discord for a few days and you'll see people constantly nagging for weapons, wings and new sets. Plus it's
cosmetics only, not like someone who bought an apparel got a major boost and put others at a disadvantage.
I don't get the hate on golden stall. Again, it does not provide any combat boost, it's just a small way to reward consistent mallers in making their stalls more noticeable (and it clearly works). Again,
cosmetics only.
created shop with gems OMG
This one's arguable, but to be fair, if we want to call this p2w, try comparing it with ToP. Back then, mall had Azreal Gems which were better than any other stat gem obtainable in-game (Cracked, Chipped, UG) and it was limited to mall only. Broken/Cracked Gems are very useful for new people and maze characters and as you can see they also increased Ref price which is something people have been asking for for a long time. This isn't cosmetics only, but it doesn't imbalance the game at all. If UGs were in mall, that would be a whole 'nother story.
And to the post itself, let's be professional for a moment. How do you expect the server to be up, stable and have frequent updates if it doesn't generate revenue? You should be happy that mall is being promoted in healthy way. IGG's done it by adding all the best items and gems in the mall, PKO's done it by adding mostly cosmetics or small ways to help newer people catch up.
