This is the thing with Knights actually being able to do cartwheels and swim in their armour, but yes. People grossly overstate the weight of medieval armaments in general.
No, they're just confused as they don't possess the necessary knowledge. Armor was cumbersome and unwieldy; but it was specifically referring to jousting armor which is both how and why that narrative entered popular culture given how prominent that sport was in the era. As it turns out jousters didn't really want to die or get severely injured for sport, so they were wearing so much padding underneath their armor that being hit or falling off the horse could at least be mitigated. This however meant that they needed help from others during the event, for example to mount the horse.

-[X] If we've got vampire troubles, maybe you should spend some time investigating how to counter vampiric infiltration.
-[X] The Wurtbadian Watch is now your pet. Given more time, you can make it your attack dog.
-[X] Write In: Given the many forms and threats of undead in the region, perhaps it might be useful to have a dedicated unit to track them down and dissect them to learn how to better kill the things, how they might form, and how they might disguise or hide their nature, so as to actually push the undead back permanently. Something like what you did together on the transformed servants, but on a bigger scale.
-[X] Write In: While we're working with the Wurtbad Watch, the theft of the documents has made it clear that Stirland needs Riverwardens. That having been said, we also don't want to further alienate the veterans of the WW by forcing them to ignore Wurtbad in favor of watching the waterways, so we're asking for Van Hal's permission and Gustav's assistance to set up a province-wide network, similar to that of the Road-wardens. Except with boats.
