Ok i play a enhance Shaman on Vcn and there is a run speed bug for them not much but it allows you to run at 40% speed out of ghost wolf
1) you need to duel a druid
2)Once the duel starts get in ghost wolf and get the Druid to put on the roots buff that they have
3) Attack the druid until you get rooted by it
4) When you are rooted attack him to get out of ghost wolf
And there you go you should be able to run 40% faster, Hope this helps
