Basically, the runes drop a lot better (you get a lot more "touches" with the advanced and legendary runekeeper) at certain times of the day.
The trick is to find out when these times are, and to start runing as hard as you can, trying to get more "touches".
Then stop at a certain point, when you are not getting anymore. These are the "gaps" inbetween "touch points" when runes and frags will drop.
I can talk to you more about it in-game if they let me back in.
An average of 1m gold / frag is exemplary.
2m gold / frag is quite good
3m gold / frag is average.
4m gold / frag is costly but sustainable.
Anything more than that is not worth it.
