If someone wants to log in and fish from day one till their fingers bleed because that's their idea of fun, then they should be able to. If RMT come along and try to take advantage, then they and not the innocent player, need to be dealt with.
But they were dealt with. You may not like the way they were dealt with, but you go to any other mmo and try to tell me they don't have limitations for new characters that were largely put in place because of RMT trouble. After two weeks the OP is going to be able to fish as a normal player, which is more than he would have been able to do if it was still the way it was when you couldn't find a quiet corner of Knightswell for all the jhfjshfjshf ajhfjashfjkasd ahdfjhas hadfjasfhask in the way.
They even compensated for the loss of income by adding income to just about everything else, and putting an end to the choke hold that crafters had on the rest of the playerbase.
I don't buy that the OP is doing it because he genuinely enjoys nothing else about the game but fishing, either. He said as much in his post:
Of course, to coninue, I can't get the stuff that I need, such as scrolls and gear. I don't mind working to buy these things, but having some arbitrary limit on a decent way to earn gil is frustrating.
He's doing it because it used to be *the* way to make gil 5 years back when leveling to 20 actually took weeks because you stood around the majority of time looking for a party. It doesn't sound like he's explored any other avenues of making money or indeed, anything else in the game at all. Things have changed. The game moved forward.
So while you defending his position is praise-worthy, please remember that this isn't the same game it was in 2004. It's almost 2012, and games evolve or they die.
Two weeks isn't the end of the world. SE could have just as easily taken the Lu Shang's quest out of the game or changed the requirements to some other high level fish (which is the reason the carp sell to well to begin with) to combat the RMT. This way made more sense and was actually more friendly to the players starting out.
