Actually, I really like about this game that leveling is not as fast as in most other MMOs nowadays, which I feel are made for very impatient people. Easy, fast progress, little effort. That's not what I'd put my passion into - so I'm really fine with the slow leveling system, in the end you feel like you actually accomplished something when you have a high level in this game (in case that you obtained it by hard training and patience and dedication - not by duping, of course!).

About money, yeah mobs could drop gold, I wouldn't mind it. On the other hand, whether you get a small amount of money drop, or you get items you sell for that small amount of money - it hardly makes a difference. This game was made in another time, had its high time 10 years ago, and back then, what you now call "little money you get from mobs" was enough money to get nicely through the game. Influation came later, and that's why the money you get from drops feel like a too small amount nowadays - but this problem is player-made, was casued through massive gold-botters in the past, it is not the game itself which first created this problem. So about this part, you are actually complaining about other players' behavior.
