Taming

Im new to the group and to the game so i would like to say hello and thank you in advance for any help and info. Ive been playing wrath of the white witch for about a week now. Any tips on taming? Im doing errand #71. Ive got the green buncher but still need the turbandit. I've killed a large amount of them by now and she still hasnt had the opportunity to tame one. Is it a percentage of chance with each battle? Im just starting to feel like the game maybe glitching somehow because she fairly often will be prompted to tame others in battle just not this little bugger.
