i went into wc on my own (lvl 22 be hunter), i didn't bring a pet, so i tamed the raptor in the cave and abandoned him when i got to a viper.  i did this on my own and ive player a hunter only a little bit b4 that and had mediocre gear, so if i can do it, anyone should be able to.  altho don't get beast lore till lvl 24, gotta go find a pet to get bite so i can train it to the viper
