5.1 brought some new things for the f2p community including an undead bird of prey, exclusively found in Hillsbrad Foothills.
For all of you hunters out there, 18 new rare pets(actually 148, but we can't catch em all) have been added all across Azeroth. Most of these new pets were previously unavailable to us because of level restrictions. All 18 of these are pretty cool and some (imo) are definitely worth collecting. Just a side note, the rare Gnath (which would have been #19) in silverpine, can not be tamed as it requires the level 69 ability in order to tame. I have tested this.
If you're interested in taming one of these rares, you can find more info here.
