I wanted to add something from my experience.
I am a miner in
EU for about 2 years now. Nothing big, no HoFs (yet), but I've had some nice globals so far
There are places where some miners are lucky. It doesn't mean EVERY miner will have luck there. So it makes some sense to listen to others and mine where they were lucky, but keep on looking your lucky spot! Don't go only to where you heard someone globaled or had big sizes....
I mine where many people had very bad runs and almost always I am on +.
Miners are a bit like cats - they walk their own ways.
Another thing. It seems that some places like close to Port Atlantis are good for people with low skills. I don't want to say that all skilled miners will be unlucky there, but I think that each miner will have places with good mining for some time. I used to mine a lot close to PA, and now whenever I go back I loose.... I had some globals there, now my max is size V.
So you always have to test new lands and look for lucky spots. If you don't have good run where you used to have it, just give the land some time off.... maybe resources will be back. If not, change it.
What to do then?
It is always good to go on a journey to the unknown. Pick a spot on a map and go mining where you have never been. Even if there are strong mobs you can avoid them most of the time.
