Ok so heres my little neck of the woods for herbing some Icethorn and Lichbloom. Its an easy circuit if you've got your epic flyer.
I do it on my druid so very easy. It has a decent amount and a reasonable respawn time. As an inscriber I basically run a circuit, sit down
mill and make w/e inks then run another which makes it a little less tedious.
CIRCUIT AROUND ENGINE OF MAKERS - STORMPEAKS
Basically just circle the entire area hugging the mountainside
towards the end do a quick glide through the middle
of the flying drakes area.
There are a number of reasons this spot is also good as it is the area where the Time-Lost rare drake spawns that drops the rideable drake and
also in the NW corner ive seen the rare elite Dirkee pop up though he only has blues I believe and a bag with gold etc. So I just hit my
/target time-lost every now and then while flying around and got him one time though missed tagging it to a paladin.
