We have nightmare whos stats are the equivalent of a drake so why not just make a drake that is tamable

Slippery slope is why.

If we can tame nightmares that are the same as drakes, why not tame drakes?
It doesn't make sense that you can tame drakes but not dragons. GM tamers should be able to tame dragons.
People should be able to find a special item that lets you tame the Destard Guardian.

Etc, etc. Not saying that that's guaranteed to actually *happen*, just that someone will eventually request one more thing be added, etc.

Also, the Nightmare's a ******* to tame right now.
