Not a prob, they're fun for when you just wanna run around and punch the brains out of stuff, stand quietly and consider life in the middle of a forest retreat roaring inferno, tackle sasquatches, or my most used reason: rescuing bodies/gear from horrible places. Like the dorf I equipped with artifact goodies, trained, did some bandit hunting in the area, fleshed out a bunch of troublespots on the map, headed for the nearest lair and stepped in goop that left me unconscious in a fever til a scorp killed me... angel was handy for retrieving the stuff without dying in the process >.>, but they are relevant for the thread actually!
Momentum is king, and even if you aren't very large, you can in fact tackle surprisingly large things as long as you're made of steel and moving at 6.666 speed... which seems like a good reason for a kisat dur practitioner to invest in armor user skill and plate armor.
Oh, and technically it is a bug, but I feel like it could be justified as a technique, though I'm not sure what to call it.
If you put a shield in your backpack along with a weapon, remove the weapon, then pick up a couple of rocks/remove them so you have two in your offhand, you can remove the shield and hold it in the same hand as your weapon.
Why, you ask?
Once you drop those rocks you've now got a free hand for grabbing weapons/armor/climbing/etc, while still having a weapon AND shield handy.
