You won't find many Paladins using this sword anymore. The weapon is still popular, don't get me wrong...just with Shadow Knights....as for Paladins? well...

Honestly, I think the 2 weapons are pretty much on par with one another, with the Mace slightly more powerful. It is the price that makes the Mace commonly used, and leaves the Sword collecting dust waiting for a Shadow Knight in the bazaar.
