I have a few gurreck, rancor, and blurg clones I made before the patch.. Are they still any good for selling to MCH? I don't see a MCH online right now to train these things so I don't know if they still work. I know the blurgs are bugged, but the other two?

Pre-patch gurrecks and rancors are as good as they ever were. Lots of MCHs, however, are looking for uber pets now.
