I believe that Emereus’ dialogue was already changed to say “Silver Lance” instead.
Giving enemy Knights and Generals access to swords would help some effective weaponry like the Rapier and Armorslayer deal more damage, but this would also lessen the primary Hammer niche of axe users. Plus I feel that I added enough enemy variety in maps to the point where sword-armors wouldn’t impact things too much. The animation isn’t the problem, it’s just that such a change wouldn’t dramatically alter the gameplay in a meaningful way.
Dracoknights, such as Minerva, don’t actually have a crit boost. Wyvern Knights are a part of the “Critical Force” reclassing set along with Swordmasters, Berserkers, and Snipers to add some variety to that reclassing pool. It’s locked to characters like Navarre and Jeorge to let them become fliers if you really need that type of utility.
Anways, just like GhostCreator said, you have to patch it to the US version.
