Here is an easy way my friend showed me to get on top of stables. The other way was kind of junky and I didn't like it.
Basically, you just use the walljump-position-helper-macro from http://www.mmowned.com/forums/wow-ex...per-macro.html and you use either an angle of 0.01, 0.02, 0.03 and do a LONG jump to get on the little lighthouse thingy. After that, you just do a normal forward 'short' hop and walluh.
I find this very easy to do, video shows it all. Should be up soon, just needs to pass youtubes thingy...
Sorry if this is a repost, I searched but only found the other harder method that had been posted.
