Very simple trick which surprising a lot of people don't know about (maybe there dumb or maybe this is an exploit).
While your sprinting you can use burnout to restore 110 ap for the cost of your health. This is a very good kiting mechanic if not a exploit.
The reason i say it could be just a tip is that you can also use AP pots while Flee'ing so who knows:S.
Anyways have fun burning those bastard witch elves.
