I don't see why the 'nerf' would be very bad.
I am playing the game normal, help people getting masters in Cathan missions (timed, so leave loads of white on the ground) and still manage to have to have a decent cashflow.
In real life, I have to work for the money to pay my house, car, electricity, new editions of Guild Wars

When I want an Aston Martin, I have to get an other job or save for a couple of years / decades.
Or get lucky and win the lottery.
The same applies to GW.
When you want something special, you have to work for it.
Farming only excists because people want something special 'now'.
Or within a short amount of time.
And since those specials are rare, this will increase the price.
I have a couple of greens on all characters except my Rt.
Most of them dropped for me during normal play or 'farming' with hench.
I have bought several, but only the cheaper ones (think Willcrusher was the most expencive, bought at 2 ecto, around 12K back then).
I have generated some extra cashflow by soloing for a 15K Kurzick armor, but then Amber prices dropped and most of the cash went to deposit.
On an avarage week of playing, I can generate enough cash for one piece of 15K armor. And that's evening / weekend play since I have a full-time job.
That's about one month of playing before I get a whole armor.
I think that's decent.
Compared to the real world, you could say that I have a somewhat above average income, have a decent house and car and some pocket money.
I can buy my GW copy without saving, but when I want a new computer I have to put some money away for a couple of months.
The farmers want to be little Bill Gates' and Richard Branson's.
They want private jets, loads of cash and stocks and be able to buy whatever they want whenever they want.
There are few people that can afford that in real life, so why should that differ from Guild Wars?
