Talk about going to extremes, yeeesh.
No, obviously not. Dragons should be the exception, as they are in all myths. The fact that dragons can be penned so easily just shows that in Wurm a dragon is just a wolf with wings. You in fact proved my point that dragons are nothing special in Wurm, and thus shouldn't exist at all (in their current state).
A wolf with wings huh? Obviously you've never encountered one. And really it's time to stop all the crybaby jazz. Ever hear "careful what you wish, you just may get it"? So much crying about penning this or that, well I can assure you there would be just as much crying (or more) if you got your no pen wish. "I can't terraform my deed because of this unique", "I've lost all my stuff and can't find my corpse because of this unique". Really it would get as annoying as this thread. Now I'm not for penning everything but I'd rather see uniques harvested and aged and killed for loot and respawn after death. Give us a reason to kill it and something to look forward to in the future. Though the sight of uniques destroying everyone and everything in their paths would give me a good chuckle. Other than that, sure, 1st to reach it and perform the difficult task of penning it wins.
