It's no good saying "RMT can do this, RMT can do that" because RMT AREN'T doing it, and that's why the economy hasn't been wrecked yet for gathered materials. If RMT did what you said nothing you can gather would be worth anything and SE would be forced to make drastic changes such as limiting the amount of materials gathered even further than now. What you're asking for is all mats to be made pretty much free. That's not a healthy economy.
I think some people just don't get basic economics on these forums. When you flood the market, the price crashes. Allowing you to bring back 300 walnut logs or iron ore per day is not going to help you, it's going to make them worth nothing. Then you'll not even want to gather them to craft because your time would be better spent making money other ways and buying them off people stupid enough to gather worthless items.
It takes what, 300 yew logs to get from 30-40 and 600 walnut to get from 40-50? Do I really want to be able to gather all of that within a few days? Why bother playing botany afterwards then? To sell logs? No, the market is flooded now. It's no good saying "not everyone sells their materials" when you've not levelled a gathering class very high. You WILL be selling your materials because you will get way more logs than you will ever need taking botany to 50. The same applies with mining and any mat obtained there. You will want those materials to be worth something when you go to sell them correct?
I think I'll just leave this thread now. I've made my points and some people will just never get it.
