I get little interview with Paul (Jagex staff) this morning and here is some info i got, it is not word for word transcription but more my interpretation as we talked in Runescape chat and its not possible to save history.

Q: People are upset as they say that now gaining levels on high lv ores is harder?
A: It is not true, it is actually faster, High lv ores was rarely used for leveling, whoever was power leveling on this ores was going much slower then people who have mining lower lv ores, as this rocks was fey and was spawning much slower.

Q: What is advantage of mining gild and heroes guild after patch?
A: Mining guild have many, many coal rocks near bed and there is also bank in middle of run too
And as for heroes guild it is only place to find runite rock out of wilderness !

Q: Why you removed Mithril and Adamite rocks?
A: As you can get them much faster now we needed to make them spawn slower or to move them farther away. Changing spawn rate was harder to do and as we needed a fix fast we decided to move them.

Q: Do you plan to add more modes to remove fatigue? Like prayer, foods or potions?
A: Andrew wish to keep cooking and herblaw distinct and fatigue is going under cooking so no potions. As for prayer, it is possible, but as this is not so simple and require changing of code, we have to plan and add it to “To Do” shedule what is not so easy. As for food Best Pie now can heal 8% and Anchovies pizza heal a same amount I think.

Q: some people liked first patch more then this second one why you changed it so fast in place to fix a first version?
A: First version was totally unbalanced and you was been able to get ores 5 times faster then before. That in long run was able to destroy not only economy but also skill balance and hard work some people invested in levelling this skills.

Q: I see people are still unhappy even if I think it is because they don’t understand how new system is working do you plan any more changes ?
A: Yes! I’m still running checks and we are looking to other solutions to make people understand that this was necessary change that will help all in long run.

Q: This is not question but more suggestion as I think people need some Shark “Paul” pizza to remove fatigue on field.
A: Lol, we try to promote less used foods with fatigue and fishes already have its role in game

Ok that is more or less all I hope I don’t forget something important and that I don’t inverted meaning of something with my bad English. BTW I also get in touch with Andrew later and he looked quite interested to add some more “miners” food in game!!
