For grinding output > gathering since output raises the number of atempts you can do while gathering only lessens the remainder loss per hit.

Also, its interesting you find a spot with 3 mining points close (like iron lake often has)...no matter if mining or quarrying point because the point resets after you finish another 2 poinrs so you can just rotate at these 3 points. Also, if you have crafts r10~15, yoy can do guild tasks...completing the r10 ones as mine will give miner the 500sp reward. You can do up to 11 guild tasks daily, which means 5500 sp daily without having to worry about gathering fatigue. I've been doing a bunch of guild tasks daily as FSH.
