These arguments are pure ignorance. Not everyone runs around with that kind of gold. Using it as an excuse to screw the casual gamer is ridiculous.
I finally get a recipe for a halberd. To make 1 it will cost 600 gold. That's more then I make in a few days. I don't grind gold and I don't think it's acceptable to make me grind gold just to make an item on equipment I built myself.
Yours is a completely ludicrous change and your excuses are as well.
You want to stop guilds from farming large amounts of gold, then change the mechanism they use to do it. Not completely screw the casual gamer.
Let's look at what the change does.
The people farming gold just keep farming gold. They might have to farm a little more but the crafters they support won't notice a difference.
Mean while the smaller crafters who have been starved of recipes because of the idiotic drop rate are now even more disadvantaged as they don't have someone grinding gold for them.
Your change just screws more of your player base then not.
