[member="Ordo"] - So by that logic you headbutted a star-destroyer and it won?
For me? It depends on the flow of the fight. I'm not going to list how a character has been hurt and how many times. It happens. [member="Reverance"] karked me up royally on Selvaris as Ijaat. Julius hasn't had a good fight yet, so I'm not sure what will happen. I tend to go more for what the story dictates. 'You cant hit me cuz muh skillz' is an excuse for lazy writing, imho. I've seen people who've fought longer with swords than I have been alive get knocked good because they weren't prepared or thinking the way a first-day student acted.
Also, FU rank or post-count, which some people take as a badge of ability, means jack-diddly in a fight as well. Just notates the strength of your abilities. That Paddy can and probably will get in at least one hit on your Knight or Master. And there are PLENTY of book, comic, movie, and other media examples of this for Star Wars. And a ton more in real life.
So, quick answer? I take damage where it makes sense in the story and helps the thread. I work with my opponent if i'm going to avoid a particularly cunning hit or overcome a defense... 'Hey, I like that you did X here, but I really want to try doing Y after/because of it, so do you mind Z instead?'.... You'd be amazed the mature and level-headed responses that gets you. And when it gets me petulance and snark or attitude? That's when I just nope out of the thread.
