Those level 200s should learn to fcking pace theirself and have fun instead of endless farming, I cant imagine the game being any fun if you are that obsessive about it (the lvl 200 guys).
To be fair there are dozens of gametypes to earn money from. Its just not always as profitable, but does that really matter so much? Do you really have to have everything right now, instead of saving up for stuff over a longer period making it actually worth something. Well play it as you like ofcourse but I think any game gets boring after so many hours. You probably got more hours out of this game than many other games, so you cant really say rockstar didnt give you value for your money. They couldve just gone with gta 4 style mp again so atleast give them the benefit of the doubt and have a little patience for the rest of the stuff to come.
