DH runes or traveller runes for PVE?
If you are mainly interested in exploring Maguuma you could consider getting the Speedy Mushrooms mastery. They give a 40% boost to swiftness for around 15 seconds and they are around every corner.
yea if maguuma if youre concern then youre fine. those mushrooms are everywhere, and when youre not using those youre gliding.
btw I forgot what DH runes do
175 ferocity, 100 power and 5 stacks of might when you lay a trap. I have the speedy mushroom mastery, but they are not everywhere ;-)
