Sooooo much text Regole haha =)
It makes no sense to "play" a game and buy everything from the marketplace.... the point of a game is to progress by doing something not putting your money in and buy everything with some mouse clicks.
If you don't have the time to play a game or decide it is not worth to farm something, than stop grinding or stop playing that game.
It is clear that someone with more freetime and effort will achieve certain things faster than others with less time, but exactly that is the point in an MMORPG and many other games!
You simply should not be able to buy everything straight with your money! The point of a game is to invest time and get things done by your own.
In my opinion, there should be a nice balance between items/things you can spent your real money on and things you just have to invest your time in to get them.
