Fast running (marauder)
if you pop charge! and then flee afterwards flee cancels charge! and you run at normal flee speed, but if you do it the other way, you can pop flee and since it doesn't cost any action points charge! afterwards and they both remain for their full duration and also stack.
With this trick you run faster than a mounted player and are easily able to get for example the mourgraine artefact nearly 100% of the time.
hope this helped you
