Neifel giants suck?

[PvK]

Ordinary Jotun giants are plenty deadly, even without very high attack or defense. Not only do they have high resistance to damage, but they have very high strength and huge weapons, which squash other units with ease. I've lost many good units and decked out heroes to them. I haven't encountered Niefels yet but with blessings they sound like they could be very potent.
