I did WALSTIB on three toons and had two more almost ready to get it when I found out that the VPD would no longer give Master Riding for free. Ah, pity. The mage and DK probably won't ever do that (though I could afford Master Riding on all my toons if I really wanted).
And I did the Wintersaber quest before they changed it to match the raptor quest. The only way I found to make that bearable was to do it at the same time as I ground out Timbermaw rep and to time my runs (I got it to 15 minutes/cycle for an hour or two).
